Caltracs with multi leaf springs??

So it sounds like the split mono spring is the ultimate set up to use with Cal Tracs. I'm just wondering how many of you folks are using them with multi leafs and how they are working out? What is the real advantage of mono vs multi leafs? Anyone do a direct comparison of the two setups?

Re: Caltracs with multi leaf springs??

I ran both and ended up with the stock multi leafs. The split mono's are very thick and stiff. If you have a ton of power they do a better job of controlling the chassis separation. At my lower power lever I wasn't getting enough chassis separation even with the softest shock and bar settings so I switched back to the multi's.

The split mono's are a great set up for sure, but not a "must have" IMHO.

Re: Caltracs with multi leaf springs??

I wound up with Greg's old split monos. But I run Slide-a-links (very similar to Cal tracs).

I ran both the split monos and multi-leafs with the S-A-Ls and honestly, it didn't make a hill 'o beans.

Re: Caltracs with multi leaf springs??

Thanks for the comments. Makes me more comfortable with decideing to go with them (I think I will be ordering a set soon). As You guys both have have a ton of torque more then I do mine should work just fine without any issues. Thanks gentlemen. I'm having trouble trying to figure out why I can't get a better 60' then 1.7 car seems to hook okay as it pulls the front wheels a good 6" (but then drops quick, not sure if brakes loose but keeps straight) pulls like an animal from launch to 7000. Hoping the Cal Tracks will give me something. Car runs 11.6 at 120 so my 60' should (in my opinion) be in the 1.55 to1.65 range. Go figure.

Cheers

Re: Caltracs with multi leaf springs??

1.7 without Cal Tracs? You must have something else on there now with your multileafs? I fabbed an adjustable pinion snubber to do me while I save up for bars. Works pretty good though so I might just keep it this way.

Re: Caltracs with multi leaf springs??

Not too sure how I ended up with the double post but this should take care if it. Yes I'm running slapper bars (Comp Engineering) now and set pretty much up tight, can maybe slide a piece of paper between the snub and the spring so not much travel left. And I forgot to mention the 11.6 is with a 150 shot of juice as the car by itself only runs 12.5 at 109.

Re: Caltracs with multi leaf springs??

I run Caltracs on a multi leaf set up and love them. I lanch at 5200RPM on the two step with very little wheel spin. That is with a 4spd MT.

Re: Caltracs with multi leaf springs??

sneaky, you may want to just try adding some Rancho's to your current set up first and see what they gets you. I actually loved my slapper bar set up but it got to where it didn't hook consistantly. Thing is I had stock gas shocks on the back and never tried adjustables. The slappers produce a really hard hit and an IC way to the back. If you put some Rancho's on there and set them to stiff it might work out. You can always add the Cal Tracs later if that doesn't work but you will have to have the Rancho's with them any way.

Just a thought....

Re: Caltracs with multi leaf springs??

Not Camaro(Nova), but my split mono's hook up way better than my multi's used to

Re: Caltracs with multi leaf springs??

Well, since someone dug up the old thread, I'll update. lol. A few years later I added a ProCharger which upped the power considerably. The factory multi's could no longer control the chassis so I went back to split mono's. They work well but the key to the whole thing is a good set of double adjustable shocks. I put that off forever trying to save money but should have done it up front.
