Ive ran both and prefer leaf springs cause they are easier to set up. Eddie

always ran a coil car myself but i talked to guys that swear that leafs are easier to drive into, but hard to drive out of and through the corner, somthing about unsprung weight, i din't understand it all, they said that there is a reason that good mods don't run leafs

oh and from my standpoint i think leafs are harder to set up(how long does it take to switch leafs and what about parts availability) coils are cheaper and most of us are poor. just my input not trying to make anyone sour!

My metric was one of those cars you'd have to put a LOT of bite into to get it off the corner. I'd set it with around 54% cross and drive it in deep. Then I would have to "toss" the car and drive it out. My leaf car runs at less than 50% cross and I drive it way on in and lift, the chassis rolls up on its on, "sets" and then I drive it out. I have much more control with the leafs on the way out. Hope that helps.

Didnt seem to notice any difference in either car just like the leaf spring set up over the coil. Eddie

[I too ran both. I didn't drive differently
because of spring type. I drove differently
because of track/setup/position in race/my own capabilities & and the cars.

Light it up, Baby!

Coils or leafs? Doesn't really matter. I have run both, with great success. With leafs springs shorten the shackles evenly. Trim 1/2 rung off both front stock springs. For minor handling adjustments adjust sway bar links or trim front coil springs. Works great with no money spent.

With coils must purchase front stiffer springs and cut rear 1/2 rung off. Then adjust sway bar or trim rear springs. Works fine.

If you have to drive it different it is obviously wrong on the set up. The tires on any dirt car do all the work, you change things to make the tires work better or worst. If you are tapping the brakes you are shifting weight, you are just compensating for something set up wrong. But no, you shouldn't have to drive it diffferent. Just set it up different, I always wondered the same thing and found out myself. Have built plenty of both and all win at any given time. My favorite is a 101" camaro with a metric frame though. Works awesome and looks great too. Just personal preferance as to what to build. Some tracks one week a leaf is unbeatable and the next week it is a coil car.

I havent driven a coil spring car much but what I noticed was that the coil car got into the corner better but didn't have the bite of a leaf spring car coming out of the turn. Very easily could have been setup problems with either of them tho.

wow - i thought i was making driving adjustments based on how a particular car was handling at a particular time and track. when all along i should have been developing a style for each type of suspension. go figure. that explains it. i should have been using my leaf spring style the other night when my car was pushing.
and to think i wasted all that time and money on springs, shocks, and those pesky digital scales. what was i thinking?

I've built them both and driven both , the set up depends on the driver and his ways of driving. set them both up lose and go from there, adjust to the driver and track, you can always tighten.

the best in a street stock would be leafs, but the chrysler ones becasue the fronts aer shorter than normal chevy, most tracks will not even notice if you change them, just move the brackets so that the chryslers fit and you still have your wheelbase. the reason leafs are better is because the thrust angle is much greater with leafs than it is with the stock gm four bar. the thrust angle being better will igve you a ton more bite. and make the car roll more.
the chevy leaf is a better choice than a stock 4 link, and a chrysler leaf is a step above both.
