I have a classic WRX and steering wheel shakin at low speed, and high speed fades in and out. I have Brembo 4 pots, all serviced and pads bedded in, I have changed the Rotors red dot 320mm, I have clocked the rotors on the car and no warp, polly bushed wishbones, balanced wheels, balanced tyres, new tyres, changed gearbox (shakey diff), one front drop link, anti-roll bar bushes going to be next. I cant find any other loose nuts, ball joints or bearings and shocks are not loose or giving in any way. Please help, this has P-----d me off since August!!!!!

When did you have a geometry check done?? If not get one done.

Next Question, Where is the nearest garage that does Geometry set up on WRX classics From Swansea area?

Have you changed your wheels from standard? I upgraded to 18” wheels but had slight vibration, all balanced fine, all wheels & tyres new etc etc. When I recently changed all 4 tyres R-Tec found that my wheels had no spigot rings in. This meant that the wheels were not centralising on the hubs correctly and only the wheel nuts were centralising them and taking the complete force of the wheels on the road. Was quite dangerous.

Will be worth taking a wheel off, measuring the inside diameter of the locating spigot rings and your hubs just in case. When you put the wheel back on it should push onto the hub and sit central without nuts, rather than the nuts having to pull it central.

Mine all fixed now and drives perfect, no vibration at any speed!

Worth a look. Cheers. Andy

Thanks Andy for your reply, but the wheels are 17" and have bin on the car since I've had it nearly 8 years ago, Will check though because they are not a standard wheel "Technocast" I've never heard of them, were on the car when purchased!
Could a wheel bearing pass the normal shaking by hand but be sloppy under driving forces?

Yeh could easily be a wheel bearing or a CV joint. Everything is put under much more stress when driving. Worth inspecting them to see if they move freely.

Could also be:
a wheel(s) out of balance mine used to go out when the tyres got worn.
Buckled or damaged wheel

If it only happens under braking then perhaps a brake/pad/disk/calliper problem, otherwise i would get the geometry checked and the wheels rebalanced and check the wheels over when off the car

re warped disk - this usually only shows up under hard braking when the disk heats right up not when cold
