I use muti leaf on my street stock..200 on the right 225 on the left..(I think it may be 200 on the left and 175 on the right) use the chryslers.. they have better forward bite..

What kind of mono leafs were you considering? I puchased a set of the landrum parabolic monos for my camaro this winter but havent had a chance to try them out yet. I've heard both good and bad about them but the reduction in unsprung weight convinced me to give them a try.

parabolics be carefull, and take your old ones with you.

i had a set last 2 laps and flatten out, actually they bent in front of the axle till i was on the ground... on a 3300 lb car. they sent me new ones.after i sent them in.. but i raced all year on my old multis for good measure.

i had 175-150 bend.

i went to 200-225 parabolics and they were way tooo soft for the same car i ran multis of 200-175.. i had to add leafs to even use them at all...

they are way softer than multis, of the same rating... id go to the heaviest possible if i had it to do over and work my way down if possible..

i think the ticket if legal is the fiberglass ones, spendy but not metal, so way light, and wont flatten out ever. supposedly

No i beleive they are shorter on the front half and longer on the back,which will require you to extend you're mounts backward to keep the axle centered in the wheelwell,but they do make a camaro type that is setup like a chrysler type,with the same dimensions so you can use stock mounts.

The leafs are farther forward which makes it stiffer on the front half,and almost like a mono spring on the back,a guy was running chrysler springs got caught(front mounts we're moved back) found those and never lost anything.

well after further investigating you can do this with regular camaro springs just move the smaller leafs forward,you will have to redrill the center bolt,or you should be able to find them from any racing leaf spring manufacturer.

chrysler springs are completely a different size.

the axle mts closer to the front eye but the overall length is also different.

A spring with a shorter front section (chrysler) will give the car a greater anti squat percentage and more bite. The tire will be planted harder by the suspension. The torque of the rear end is countered by a shorter length, so the force generated must be greater. Think of a short wrench versus a long breaker bar. Same tork is generated with different force. This countering force is what lifts the rear of the car and plants the tires. The same effect unplants under braking, though

i found the parabolics are way way softer than multi's. i would buy the stiffest and go down if necessary i think they go to 275?

chryslers fit chryslers, or modifieds. thats what they are for.

camaro springs are 25" from center pin to the front mount,chrysler's are 20".

I have seen the difference first handle between camaro and crysler leafs. Cryslers are MUCH better. And if this has been explained yet, the portion of the spring fron the axle foward is the part the does the lateral location and traction, the rear does the spring action. And yes the Cryslers are one inch longer over all. The rate depends on the track size. The 200 and 225 work well on bigger tracks. On the 3150 lbs stock stub car my brother ran, we had were down to 150 lbs rates on both sides. This works better on a small track like a 1/4 or 1/5 mile. The track we race on gets very dry slick too (BLACK slick). Hope this helps.

Also, unlike coils, let the rear hang in between races. Leaf springs can settle and you'll get more life from the if you keep the weight off when your not racing. Cya
