an easy up shock would be the best on the lr for slick track. so that would be a stiffer and a softer shock.....

Softer shock get it there quicker and stiffer
rebound keeps it there longer.

That is what I thought. Now tell me this.

I was told from a local raceshop employee that my reverse spring split was making me tighter through the middle of the corner, b/c it was allowing weight to transfer too quickly to my lr. However, I thought shocks controlled the rate of transfer.

Then, he also said that the soft rf let MORE weight transfer to the lr. Meanwhile, I'm thinking just the opposite.

Any comments?

I agree with dirtracr, I tried some of
that reverse split business and I did not
like it. Couldn't get up off the corner
on a slick track. My opinion is the stiffer
right front helps to load the left rear more on the way out. I see a lot of these late
model teams running reverse split across
the front. Can anybody explain why??

Late models run the spring split for different reasons. For one, most have 4 bar on left rear. The softer RF lets the car roll over more so the LR can get up on the bars and lets the wheel walk up under thus giving more rear steer to help through the turns. With those wide tires and 4 bar suspension, a stiff RF spring would make them too tight.

I have also run a 650 rf and a 700 lf it did free the car up 225 left spring behind 4-bar with a z-link rr but i never did like how the car felt on a slick track off the corner i could tell i lost bite off the corner and down the straight 175 right rear i guess if the track is flat it could work but the tracks i run on all bank even down the straightway

The reverse split works good on a car set up for it. The biggest problem with using it is a car set up right for reverse split is VERY fast and stable at WIDE OPEN THROTLE, but it gets ( the best way to put it is) SCARY when you have to lift. When you drop the pedal the car gets hard to turn and very very twitchy. We used it to win a few races but it you were going into the corner and had to lift you were going to go straight. We (read that I) decides to change back when we were winning every race we finished. (read that as 3 wins 5 times into the wall) The best pat is for some reason when you lift the car seams to completely forget what the steering wheel is for, and if you hit the brakes it dose all kind of weird things. In a heat I had to go hard on the brakes comming out of two and ended up in the infeild but the car spun around on the right rear tire, The front went pu the track and it spun on the right rear all of the way around and slung the car into the infeild.
It was fast though.

OK, here is my opinion on this topic. The springs in the car tells the transfering weight where to go. The shocks are time timing devise on how fast the weight gets there and how long it stays. Now that being said, as the track dry out most guys soften the comp. on the right side and increase the comp. on the left rear. Most race cars of today are very dependent on rear roll steer and the controling of the roll steer. On dry, slow track if the car comes off of the right front to fast it will get tight in the center of the corner or have a throttle push. By softening the comp. and increase rebound on the right front and increase the comp on the left rear the car will stay on the right front tire long enough to get throught center of the corner. It will help roll steer stay in the car longer. Now I have a different opion as to getting the car off the corner. If the car enters the corner and turns in the middle good, it's the drivers problem to get it off the corner. You can have the best set-up off the corner but if the driver can't drive the car straight it won't matter. I believe that 80% of corner exit, on a slick track, is the ability of the driver to be straight. The driver must not drive the traction out of the car. like I said this is my opion, what are the thoughts?

We run reverse split on front & even to 50lb heavier on lr & have found the front split helps turn in & rear gets left tyre working coming off. The way I see it, if you put both springs on scales with a plate across them & stood in the middle of the plate, the scale under the heavier spring will have a bigger % of your weight. We have also spent a lot of time getting the shocks to keep the car stable.
that,s my 5cents

That is wrong in sooo many ways.
