leaf car questions

[Wrenchead84]

hey everyone. thanks in advance for the help.so we bought a nova last year did pretty well in it, 3 feature wins..., anyway, this year i want to step it up a bit. i have yet to scale the car cause i know nothing about the % to run.----ill start with the car3200# rule lead allowed - we weighed closer to 3380 at the track---900 LF 1000RF----200 LR 175RR----we will be using QA-1 this year (havent yet) 7/7 LF 7/3RF 3/5 LR 4/4 RR. --- 215/225/235 70 series 15" tires allowed 7" wheels beadlock ok. --- we run 225's on left and 235's on right so far. -- 2" offsets in front 3 " in back - in feature we normally go to 2" LR with 1/4" - 1/2" for tightening. -- track is 1/4 mile high banked - usually rough and very dry slick for feature. --- problems i noticed last year - car was tight in center which made us loose off exit. we added a spacer to the LF and moved some lead high and to the Right Rear which seemed to help, but im still looking for more bite as others can get into the gas harder and sooner than i can . making me need to run them down-- what do you guys think?? i hear all these tricks with cutting and modifying leafs and using different control arms up front to help with cast/camber but i don't know what they are

Are you leading the LR at all?

[Wrenchead84]

im guessing youre talking about rear steer? rearend is square within 1/16th of an inch

[klv8lm]

Put the LR ahead 3/8". I would also put 2" offsets on both left side tires and 3" offsets on right. How much stagger are you running? You really need to scale the car to know how much LR bite you have and how much rear and cross is in the car.

i starting to realize the scaling is super important. i have yet to scale the car. other than knowing how much lead i had to add to be legal. running a 225 on the left and a 235 on the right, i'm guessing the stagger is a little over 1/2"

[Wrenchead84]

I should also mention the car is currently getting a new rear frame an built. So it's in the tear down phase. But I need a starting point for my percentages for when we start putting lead back in the car

[klv8lm]

This is just a starting point and you will have to go from there 52-53 % rear. 51-52% Left and 51-52 % cross. Also Measure your tires, I have seen an inch difference in the same size tire, try to get 2" if you can.

sounds good thank you. ill re-post once the car is back together and we get it on the scales

[Wrenchead84]

also, with the weights i have posted, would it be better to go with a softer front shock setup like a 5/5 LF 5/3 RF or keep the firmer ones i posted earlier which were 7/7 LF 7/3 RF??

[klv8lm]

Try both and see what you like better.

[Wrenchead84]

That's a costly venture . What would running the softer shocks do vs. the stiffer shocks

[klv8lm]

Softer shock will speed up the motion

[Wrenchead84]

So more dive and more weight transfer?

[klv8lm]

Not really more, just quicker..

wont leading the LR make the car even more loose on exit?
