What shocks to run on the Demon

The Calvert adjustable rear shocks work pretty well on my car, especially when the track prep isn't up to snuff. I have their fronts also, but I am thinking of going back to stock replacement as they rise too quickly.

Stick and radial is a tough nut to crack. There's a LOT of 60' in getting the right clutch. The hard hitting on/off sintered iron style thing is not what you want. Adjustable is ideal, but $$$. Your trans and rear end will last longer too.

Back when I had the same issues with a Ford, the single diaphragm clutch I had the best luck with was a hybrid disk with a Mcleod pressure plate. An aluminum flywheel was a big help also. It's all in trying to lessen the shock to the tire. I don't know if its an option for you, but with the Ford, I had positive results going from a 3.35 to 2.92 first gear (I don't know what the mopar ratios are, I'm a torqueflite guy). HOWEVER, its Probably cheaper to buy an extra set of rims, some stiff sidewall slicks and a gee-whiz aluminum jack though....

Get a pair of rallies or some cop wheels and throw these on it:

Your 60' issues will disappear like a bad memory.

But if you insist on the radial, remember:

Radials like a lot more pressure than bias ply, and they are a lot more sensitive to track prep. I ran my 275/50 at 20 lbs. Even when they are working well, radials are not very consistent.

It should be noted that radials are also much harder on drivetrain parts than bias ply tires. I don't know whether its the stiffer sidewalls or just the greater weight, but you break a lot more stuff with a radial than a slick (when it starts hooking that is). If you are running a radial and feel it start to tire shake, you need to get off the gas with a quickness. Also a good idea to make sure your perches are welded and I'd put some kind of reinforcement on the spring hanger as well.

Have you checked the pinion angle and all that?

Have you got poly bushings in the shackles and such? If you've got rubber it is deflecting massively when you drop the clutch and certainly not helping.

Beautiful car, BTW.

Good Luck!
