Hi all, ive got a 2WD sapphire and when i spin the wheels its like the back end is jumping/juddering which i assume its axle tramp? Am i right with this?
If so what could be causing it and how could i cure it?

I had toyo proxies t1r's on for the past couple of year and just put fresh bridgestone adrenalin's on and its done the same with both tyres.

Thanks
