Possible causes of wheelhop...

[gixxer750]

OK.... A question. What causes wheelhop?

1 I have stock struts, they are not blown.
2 I have brand new Eibach Pro Kit Springs
3 Kumho 245/45/17 MX tires
4 New Driveshaft bearing
5 4.30 LSD diff



Car wheelhops on hard launches, or when shifting into second or third hard. It did this before the lowering springs. I set the TEMS to full soft and unplugged the connectors, it still did it. I held the throttle wide open with the key on, set the TEMS to full hard and unplugged the connectors... still got wheelhop.


What is causing this?

you need traction arms! hit up horsepowerfreaks.com for those!

 

[Justin727]

btw how are your rear sub frame bushings?

 

[gixxer750]

I need to check on that..... Does energy suspension make a full bushing kit for our cars? I would be very interested in that if they did.

I'd say that it has a lot to do with the geometry of the rear suspension, not the equipment you're running.

Energy Suspension does not make a bushing kit. Ronnie K makes a poly bushing kit, available a individual pieces or as a set. There is also still 1 set of Nylon bushings available from the SOGI group buy years ago. And Superpro makes a couple of A-arm bushings, but they aren't likely to help you here.

But the first thing I would check is to see if your stock traction arms are bent. Anytime you get wheelhop, they are likely to bend -- especially the passenger side one. Look into replacing them with the LIPP or A1 replacements (or CFX).

Haven't done any hard launches as I don't want to kill my Torsen but nailing it from a roll I don't have any hop at all with the Lipp arms.

It hopped like a bitch when it was stock arms and NA!
