I am currently running a 4-bar left rear,two-link right rear with a Afco progressive torque link spring.I am getting 2" of travel.Without any other changes,what would going to a 1050 or 1200 torque link spring do?Just trying to make car better.

a 2/4 link car needs that 2" or so travel to work, so if you go to a stiffer spring it cut down on the rear steer while on the gas. Which is the key to running the 2 link with the 4 link.

If you get less travel, the car will rear steer less, should be a little tighter off. So maybe working with some preload adjustments, increase the preload on the spring as the night goes on.

How do you like that set up so far (the 2-link / 4-link deal)? I've been itching to go to it myself, helped a guy running it the other night, pretty wild ride looks fun.

Where is you lr spring located. If its clamped in front than a stiffer spring will add a little less bite on the gas. Otherwise I doubt you will notice much change.

I like it better than the two-link,but just need to fine tune it now.The left rear spring is clamped in front(225)and the right rear spring is on top of housing(175).I am having to ease into the throttle a little more than I think I want to from the apex out.I am running 49.2 cross,52.6 left,and 58-60* rear without me in the car.It has 45 pounds of bite.Top bar is 24* and bottom bar is 6*.

Ease on the gas alittle more that you think.

How do you mean that? Are you saying you want to get on it more and dont have the bite?

I think i would try a little more bar angle on the LR lower bar, maybe another hole when it slicks off.

Hoosier's or IMCA tires?

It does seem like I don't have the bite,and they are I.M.C.A. tires.I have a couple friends that are running 4-links with more engine than mine and they say they are just slamming the the throttle down and it stays hooked up.

Most of the guys i've seen or heard that run this 2/4 link deal run spring behind on both, and clamped on the RR (2 link is already clamped thou).

You may want to try going spring behind on both. I dont know personnally, so maybe someone who rauns it can give you some pointers.

I went to a USMTS race and every car that ran this set-up was clamped on left rear like mine is,some had right rear on top and some had right rear behind.I have never heard of the left rear clamped behind the housing.

LR behind on the cage (floated), that may of come out wrong, the above post.

No, i've never heard of a LR clamped behind myself, seen it talked about on this site before thou.

Try moving the RR behind, a guy at Midwest Motors told me they didnt care for it on the housing. Thats if you dont mind to do some 3 wheeling.

That may be another idea, call Rex at Midwest motorsports, he talked with me about this set up and he has it down.
