mine dose the same. think its the pinion bearings

Took car for its first drive today. Did about 30km in it. Seems to be heaps more perky. Track day 28 days and counting!

Im not realy sure what the suspention settings are. it has a bit more camber and a bit more caster than standard. I will post them once its had a wheel alignment done. Got a n14 pulsar radatior and it fitts pretty good. Also gettin rid of the solid fan so got a 12 inch eletric fan and thermo switch.

Thats the wifes yellow ride in the back.
The struts have standard length bodys they were slightly shorter than the 1200 ones but the inserts where way shorter. I spaced them to the top of the tube (about 60mm)and they where still about 2-3 inches shorter in overall extended length than the standard ones. Front springs are 200lbs.the rings are cable ties holding the break hoses
