Wheel Hop

So whenever my tires break loose, they rarely spin, I get wheel hop. My rear end makes clunking noises in and out of reverse already, but I've heard that's a Superformance trait. I've got Michelin Pilots 17x335 and a 3.73 rear end. It doesn't make a difference if I adjust my shocks all the way firm or soft. It seems so violent, I want to make sure I'm not damaging parts and pieces back there. Anyone have any thoughts?

Miles,
I found a technical note on SCOF about the "clunking" noise. Suspension bushings and clearances. My girl is up on jacks now and I'm going to investigate the same problem.

I've pulled the side pipes and dropping them off in Mesquite today to have new ceramic finish applied. The shop is also going to weld the rear bracket back on. You should probably fix your bracket too. I'm concerned about the pipe eventually bending if it bounces around too much.

Did ya check out my new video on the toy run thread?

Wheel hop is extremely damaging to a rear end. It will break something (spider gears, half shafts) if you let it continue. I'm not sure what the fix is on a Superformance, but you definitely want to let off the gas when it starts happening.

You are not alone. Mine will wheelhop on any launch greater than 3500 RPM. I just try to leave at a low RPM and then smoothly mash the loud pedal.

You can switch to a sticker set of tires, change the rear end gears and or larger rear sway bar to help with wheel hop.

I was at the drags last weekend with an SPF owner who has M/T ETs and 3:73 gears. He got into the high 10s with a 427w and no power adder. very quick car.

It was painful to watch his launches due to the extreme wheel hop in first gear. I don't know the SPF solution, but I can tell you I've seen this and it is violent.

I do not think a change in gears or tires is the solution. I suspect rear end geometry is not optimized and needs to be revamped.

I hope "Greg" (the owner/driver) is able to weigh-in on this topic.
