I got wobbles Options

[94TRDcelica]

Hi, haven't been on here a while, sorry! But I had a quiery and usually someone knowledgable on here posts useful info!!!

My car at the moment seems to have some wobbles at high speed! I'll describe the symptoms:

At 60-70mph+ the car drifts slightly to the left, even if its against the natural camber of the road, and the steering wheel shakes, which is quite annoying! I've recently had new tyres fitted all around, newish suspension on the front, electronic tracking and wheel balancing before and after tyre fitting but it still occurs.

The other symptom is under hard the braking the steering wheel shudders even more for a short while but lessens as the car slows down and at low speeds, particularly on roungh surfaces the steering wheel will often dive off at an angle!!!!

I ahve however noticed that the rear strut rod is bent and i have a replacement on order, coming tommorrow and I'll see if this helps at all, although i doubt this is the only problem! I have a feeling it might just be the brakes, but would it shudder at speed when Im not braking?

I have after market alloys but have the spigot rings so its not those, im 99.9% all the bolts are correctly tightened, I just hope its not a steering rack problem...Can anyone offer any advice?

Cheers
