Southwest Speed also offers an adjustable lowering block for moving the axle back and forth. Will this be useful to dial in a little rear steer for help on slick tracks?

One more thing, I was just curious again about the rr and lr leaf spring rates. That and the coil over eliminators as far as one on the rr and what spring rate for that and the rear shock combinations that seem to work best for your car.

Southwest Speed offers the Chrysler multi leaf and it appears the locating stud in the spring is closer to the front than the one currently on my car right now. Mine is 24" from the front center eyebolt. Is that the case here or am I just seeing things. If so, do I end up moving the whole rear axle up because of the difference? Or do I have to figure out a way to move the front mount back to keep the rear end in its same location that fits the wheel cutout in the car?

So much to do, so little time....lol. I really appreciate any and all help.

I'm not sure about any of the rest of the questions but as far as the adjustable lowering blocks......when I ran mono-leafs I had them and yes they will give you another adjustment for dryslick conditions.

You have camaro leafs. Without looking at your car I would probably stay with them so your wheel well is in the same place. If you have room to move the rear end fwd. then do it as the Chrysler springs have more selection for the arch you want.
LR- Chrysler- 8"-10" arch- 165# leaf
RR- " - " " " - 50# mono
150#coil on the RR
If you run the Camaro leafs go to a 175LR and a 65-75 mono to make up the difference of the 4" in front.
Randy sells 8" arch and R.C.race cars sells 8-10" and dirtrace21 on 4m.net sells the same.

I am trying to see if there is a centering pin in the mono leaf. I can't see any in the pictures. Does that mean they mount to the plate differently? Or is there a Camaro mono leaf that I can use. So far all I see are Chrysler mono leafs.

Thanks

Is there a minimum wheel base in the modified class? My car is 113 inches axle to axle. If I could shorten it by 4 inches with the leaf spring mounts and it would help, then that is what I can do. Just curious. Thanks

The camaro's are 25" X 31". The Chryslers are shorter in the front. The steel springs for the Fat boy or whatever setup they call it modify the stack to obtain a rigid "traction bar** like action on the left rear and a FLEX TWIST like action on the right rear..........The mono leaf on the right rear should be preferably a 65 or 70 lb spring rate.

The monoleaf probably just has nips instead of center bolt. Works on the same principle.......If it were mine I would drill it 3/8 and put a center bolt in the thing.........You need to throw away those rubber insulator pads and make a plate or run the ribbed lowering block. The regular oval blocks are the best for this for they fit your bottom u bolt plate the best. Throw away those two short on inside and run 2 ubolts. The longer shackle end for the Chrysler spring allows for the use of the longer shackle setup........Put tons of arch in the passenger side........I'd make the thing another two inches longer in the back and go 14" on the arch. Just my opinion.

Dirt racer 21 and I talked on the phone about this setup and the main point is not to let the driverside hinder the car from rolling in any way.........longer shackles laid back at an angle just enough to keep them from bottoming.......ideally mounted with a notch behind so the rear of the spring can get vertically higher than the mounting point for the shackle.

I notice for the mono leafs that they seem to be normally a 5" arch. I guess I am not looking in the right places. I have heard 8" arches and now you mention 14". How can I get that much and still mount it? If the shackle is angled way back like that, how does the suspension travel any. It would seem that you are talking about a bind if the shackle won't go back any further. Or am I getting my sides and rear mounts mixed up?

"Throw away those two short on inside and run two u bolts." I am not sure what you mean by that statement. I am still planning to use a floater rr leaf connection to the rear end and a brake floater system with a coil slider. I am not sure about the shock setup for the rear, location and valving.

Thanks for the help and please, keep it coming!
