LEFT SIDE WEIGHT ON DIRT. I run a Metric chassis on dirt circle track. The front upper control arms can be relocated, but everything else, (front and rear) must have stock suspension mounting points. I have recently been experimenting with higher than average Left Side weight percentages, in an effort to use ALL the contact patches on my car 4-link suspension information. 4 LINK DIRT SUSPENSION. TIGHTEN CAR ON CORNER ENTRY. • Raise left side frame mounted panhard bar on chassis. • Lower panhard bar on pinion mount. • Stiffen left front spring. • Raise left side ride heights (rock up) • Soften 6th coil spring. LOOSEN CAR ON CORNER ENTRY Apr 12, 2011. #3. well i would think rear percentage is much more a factor. 56-60 percent is great and since cross weight is more of a tuning option i would go with bite. Most times we ran negitive stagger to tighten up the car, although now a days they run emods. I remember having 56-60 rear, 100lbs if bite with P225 LR and P235 RR This Tuning Guideline can be used for Late Models, Modifieds or B‐Mods Problem: Car is tight on corner entry, when on the throttle: Take Wedge out of Car * * 1 Add 1/2 in. wheel Spacer to Right rear * * * 2 Lengthen Right Side WheelBase (1/4 in. ) * * * At Harris Auto Racing we manufacture our own chassis designs for the Modified divisions. *Over-rail cars set 14 1/2 from right side over rail bar to right side of the torque link bracket. d.

To decrease bite: Decrease nose Increase left side weight Increase cross Tight kart has more rear grip than front Loose kart has less rear grip than front Stiff chassis is tight Stiff chassis transfers more weight Flexible chassis is loose Flexible chassis transfers less weight No Goats Racing - Chassis Tuning - Page The big reason is that the Panhard/J-Bar was probably too high to begin with and side bite is lost. The car skates in this scenario so lowering the bar creates more grip. More grip allows the driver to feel more secure so he can simply turn the car to the bottom instead of skating up to the second groove While the ideal amount of camber will vary between front suspension layouts, most dirt suspensions need at least 3 degrees positive camber in the left front and at least 3 1/2 to 4 1/2 degrees negative camber in the right front. Camber helps your tires to make side bite. Try adding camber if you need to improve the ability of your race car to turn
Managing the wedge is also helpful if you're wondering how do you get a side bite out of a dirt car because it will affect the level of traction. Conclusion Currently, dirt car racing involves a left-hand weight measurement of 53.5-55, along with a wedge between 75-125 pounds . ·. 2,171 Posts. #7 · Mar 28, 2006. Flat carpet track , L4 based car , 63-64 % left side , much more than that and your not going to transfer the weight to the rt. side enough thru the corners. Perfect world --Car should be 50 / 50 thru the corner on oval Posts: 982. Re: reverse spring split. Reply #6 - 03/03/12 at 5:24pm. Try 1000 r/f, 1050 l/f, get 7 to 8 degrees pinion angle. Get sphereical bearings for the rears of the trailing arms so when it rolls it won't bind up. Maybe try a 100#, 16 spring for the l/r, it should give you foward bite. Back to top
Forward bite is the traction the car has coming off the corner. If you have good forward bite the car will look like it was shot out of a cannon when it comes off the corner. You definatly want it. How do you get it?? Thats the 64 dollar question. If the car is free thru the turn that will help alot with forward bite coming off In short what BSB feels is the most important part of the car for making forward traction and side bite is often turned in to a marketing tool for someone to sell as a product of profit. People seen an opportunity to get into a market because building birdcages appeared to get easier to do, but the truth of the fact is it got harder to build With dirt modifieds I don't believe anyone running upfront at top notch tracks is using a car more than a year old or so in the modified division. The thing we found with coilovers was that they gave the car good forward bite, but didn't have good side bite meaning the car would want to slide more than it should in the middle of the corner.
Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube From what Wash posted, looks to me like you need to start with increasing your bite. I would up your bite to 60-70 lbs. Will loosen car on entry but should give you way more forward drive if every thing else is close. Works for me. JMO. sm44. Pit Crew. Posts: 5. Forward bite.

broken in will lack forward and side bite, until they get scuffed in. Generally speaking, on wet tracks, you want a tire with radial grooves and cross cuts in rear, and radial grooves in front. On dry tracks, we often run only radial grooves on all 4 tires. Radial grooves promote side bite by creating edges on the contac 2011 DMR Modified Setup Guide Left Side % 52.3% Cross % 49.5% Bite or Wedge 40 to 60 lbs Rear % 58.5% Modified Scale Summary Scaling Quick Reference Guide 1.

This makes the cornering force balanced from left to right and offers the best performance overall. However, many cars cannot make the 50 percent left-side weight percentage due to driver offset. Still, it is a worthwhile goal to strive for 50 percent left-side.
That forces the left rear control arm downwards and shortens the wheel base on the left side yielding rear steer during cornering plus maintains weight on the left rear tire tread for grip. 2 or 3 years after I found this works awesome on dirt, I seen dirt modifieds and late models going to light right side springs First I will say I have only been racing for about a year now, so I am still a beginner and any help would be appreciated. Most people are running clay tracks with probably lots of grip, well I am running on a small DIRT track that is usually dry slick with only one groove and that is on the bottom because all the loose dirt is in the upper groove Such a chassis can probably be made to work well on dirt where it's really tough to get too much side bite. Good dirt chassis tend to be relatively flexable. This means that when the driver is seated in the kart one of the wheels can be lifted a considerable distance before any of the other wheels leave the ground 2009 MODIFIED SETUP SHEET (3-LINK & 4-BAR) (Feel Free to Print Out) RIDE HEIGHTS-(NEW CHEVELLE FRONT CLIP): LF: 7 7/8 to 8 from ground to center line of lower A-Frame bolt RF: 7 7/8 to 8 from ground to center line of lower A-Frame bolt LR: Will be set by amount of wedge RR: 2 3/4 top of lower underslung to bottom of axle tube for under rai This term is widely used when describing a 4-link dirt modified right front shock or asphalt cars front shocks.

To help the car turn through rear steer you can run the RR trailing arm uphill a 1/2- 1 at the front. As the car rolls the RR trailing arm will push the rear end housing back on that side. The uphill RR trailing arm adds anti-squat to the car which helps forward bite under acceleration so I like to run some uphill angle in the RR trailing.

As the car rolls, several things happen. 1) The rear end is pulled to the left, tucking the right rear in, compared to the front. This helps to plant the right rear. 2) A force is generated thru the J-bar, and this force has 2 components, 1 of which forces the rear tires into the ground, generating more side bite Dirt Late Model Racing-Illinois Side Bites Get Racing Products!

For the 600cc chassis, 61-68% works best. Typically we are at 63-65%. Calculate the cross bite by adding the RF and LR and dividing by the total weight of the chassis. Look for about 42%-48% in the 600cc. For a normal track we will start at about 45%. Increasing cross bite will tighten the chassis coming off the turn on small tracks Race car suspension Class. . In order to understand the complexity of a Formula Cars suspension, a basic knowledge of the stock car suspension should first be mastered. When designing a (front) suspension , geometry layout is critical. spindle choice and dimensions, kingpin and steering inclination, wheel offset, frame height, car track.
Forward bite is slightly reduced to a degree (from Option #1), but the axle diameters here still remain much thinner than standard axles sold which will allow for axle wrap-up and increased forward bite over any standard diameter axles. Best Suited Track Type: Heavy or tack The focus is mainly the dirt late model and dirt modified race cars, but the general principles I illustrate can be easily supplied to any type of dirt race car or any race car in general. Here is just a little hint of what is inside: Why softening the right front spring will add side bite as well as forward bite to your car.

Great work Kyler Dirt Racing Tire Prep: Altering tires by grooving and siping can maximize the amount of traction and enhance the performance of the tire. (side bite) as the driver turns their car. Again, grooving helps reduce heat in the tire. It allows heat to escape from the block or the rib of the tire as the air flows across the tread The EX is a complete gummy-spec tire with a very soft tread and a fairly soft sidewall. We tested this in a 110/100-18. The traction is on par with the stickiest tires in the test. Large granite rocks or small rolling rocks were greeted with an unreal chew-and-stick pattern If lowering blocks drop either or both spring eye positions relative to the axle then the rear roll center height will be lowered and chassis roll, along with rear side bite, will increase. Too much lowering block* can cause the forward thrust of the rear axle to prevent the leafs (or torque arm) from wrapping up and absorbing engine torque

Steve Norris, crewman and tire prep for dirt late model driver Billy Moyer for over 20 years: Siping makes a tire 'fire' quicker—get up to temperature faster. Say there's a D55 tire rule and the track is muddy for the heats. You'll want a tread that's all cut up so it can move around, build heat fast, and give you some bite I race a winged 360 sprint car on a ½-mile dirt track. According to your #S282 Sprint Car Chassis Technology book, there are multiple ways to adjust a chassis to make it looser or tighten it up. For example, spring or torsion bar rates, crossweight, chassis tilt, wheel tracking/spacing, wing position and angle, can all be used
Pinion angle simply refers to the angle of the differential's pinion shaft and yoke in relation to the driveshaft. If you're running a leaf-spring car, the pinion angle is set by the welded perches on the axle housing. The universal joint is the part of this equation that allows the pinion angle to change as needed The team at JConcepts are always innovating and adding to an arsenal of fine racing tread patterns and compounds.

Grooves can also be cut at angles. Angled grooves will result in a combination of increased side bite as well as increased forward bite. Unlike siping in which you should go no deeper than 1/2 the depth of the tread block, grooving can and generally is the full depth of the tread block These dirt tires have a block-shaped pattern, both to bite into the dirt and evacuate it so the cars have grip. The size of the left-side tire also has some differences
