that thing should be so tigh comming off of the corners that it should drive you to the fence

Ok what do you mean that it wont come off the corners are you spinning the wheels IE:not enough forward bite or the motor wont come off the corner

do you have 13 inch springs or 11 or 16 what do you have for springs alsoi where is the fuel cell and battery

If the car wont come off the corners it could be such a thing that the car is actually to tight and you cant get on the gas when you want to to get the car headed down the straightaways

What do you have for stagger in the rear i know its hard to get much more then a inch on g60's but they do streach in the sun and with some diesel fuel

if you can run beadlocks drop tire to
l/f 10 r/f 14-16
l/r 8 r/r 12

weight placement looks good, also may try driving car in later and come off close to the bottom as possible..that way you can stand in it and it will catch before you get to the wall..

another thing is it coil or leaf car, and what is pinion angle set at? also caster/camber settings?

If you lower your cross to around 51 and can get your rear to around 53 w/ 100# of left rear it will help your bite coming out the corner. Thats what I would try.

This is the same springs as we have been running in our I-stock and it comes off the corner like a rocket. What shocks are you running? Are you slowing down too much on entry and not keeping your momentum up then spinning the tires? How much stagger and what size track?

i'm running on a fairly small 3/8. I can pass just about anyone going in and thru the corner and then on exit it just lights the tires up. Have about 3/4 inch of stagger. Battery is over lr spring, fuel cell is mounted to the left about level with top of frame rail. Running stock mount Bilsteins on front and afco on rear. 11 inch rear springs.

Are you over driving the car into the corner and then having to turn it and make it loose in the middle? This will cause a false loose off condition. Try going in a little easier and see how it comes off. If you are doing this you could also be killing your momemntum. Can you hold the car on the bottom of the track?

Well if you change to 13 icnk springs in the back that will help you with forward bite comming off or if you arnt that east with the gas try to gear it down so that you dont spin the tires.

Also ifyou can try to add around 100 lbs or so under the fuel cell or some place that isnt obvious

What number afco are you running on the rear? You could aslo try running easy up shocks on both fronts that will help transfer the weight quicker to the back just put them on when the track gets really really dry

Everyone thanks for the help. i'm gonna put some lead in and what do you think about putting an easy up on rf and a tie down on lr. I already have one easy up and one tie down thats why I was thinking about that.

We run a tight 5/16 mile track and you are closs except for cross weight. Try to get it between 48.5 and 50.0 it will help alot and when tracks goes dry move weight to the right side of car. Keep 53% left but loose a little cross and maybe think of some bigger springs in the back and run the rough part of the track you might just be surprised at whats up there. A tight turn will slow you down so if you can keep speed and rpm up you will be better in the long run.

Our rear springs are 16" so I am not sure exactly what the difference is between the shorter and taller springs. I have talked with different people about the effect of different length springs and I get alot of people saying that it doesn't matter the height. We used to have a JET stock car and it ran 13" springs and this same setup would not work with that car. Now we have a Larson Stock car and it is made for 16" springs and this setup has a ton of forward bite.

Is your chassis rigid? If it is not you may need to increase your right front spring to get the car to come off the corner better. I have heard of cars with alot of flex in them needing a bigger spring than cars without flex to be able to work. It may not be transfering true to the left rear spring.

Thats a very good point that should have been mentioned early in this post

Do you have good X bracing under the car where do you rear and fron kicker bars come down the four major points need to be on top of the suspension

The main thing with running taller springs in the rear is more angle on your control arms you more you get hte bettet to a point BUT there is a catch to this the car wont handle that good also so you need to find a happy medium if you want to fight it in the corners or kill them off the corners and down the strighaways


Wayne I talked to my husband about your setup and this is what he sayed.

Hey there I talked to bonnett today about this guy and by the soundfs of it he said that he isnt getting enough forward bite so have him go to 13 inch springs and make sure that he has 1 inch of rake in his car and if he wants to have him check his ride heights and you e-mail them to me or call me on my cell and tell me and we can get him figured out. Also have him measure his ride heights at the frame where the frame is level on all four points.


That is right from his e-mail this morning.
so if you can do that and let us know we can give ya a good hand

My 13 inch springs will be in on Friday. Will they raise my rear ride height and if so do I need to raise the front also.

I would put an inch to inch and a half of rake front to back. If those springs give you that I wouldn't worry too much.

NO leave the fron alone and see where you are at for height in the rear most of the time it will only raise you a inch or so BUT in some cases I have seen it raise you a inch and a half


First thing though make sure that you get you ride height measurements FIRST BEFORE you add the spring then add them and see what you gained

I know that on this new car the guys are experementing with cutting the rear spring to get what they want they are going with 16 inch rears and cutting them to the height that they want
