Vibration while driving

[otp]

Can any one shed any light. I have a minor vibration when driving around 70ish. I've replaced all the tyres as it had been standing for a long time before I bought it. This cured about 90% of the vibration but the drive is still not smooth is this a characteristic of the car?
I also have a really bad judder/vibration when braking it shakes the car when braking hard. I can feel the brake pedal pulsating on very light braking so probably a disc out of shape. Any other favourite causes I've read about seized pads and corrosion on the inner face.
I have spent hours trawling the net reading about brake discs etc mine is a 97 4.2 with 4 bolt AP calipers so I guess I have the 291mm brake discs. Do I have any options for upgrade ? I have read something about an upright change which may affect what's fitted, my car has a sticker on the vin plate which says upright recall completed what was the recall?

Any help appreciated

I will check them it has had a shaft in its history they do take a hammering

I will get the front in the air and check all the bush's , I've looked at front disc prices maybe a change to 304 with a spacer is on the cards. I've measured the front thickness at 29.5mm the rears have a small lip but they seem almost the same size as the front. I will get them measured up and possibly a skim to resurface them.

What was the upright recall?

Lincscerb I will look at the bushes anyway probably worth changing for £30. I also have non TVR alloys and I know there are spigot rings in both fronts but when changing the rears at the weekend my son ( the tyre fitter) spotted the one rear had no spigot and I noticed the the other side had been partially pushed inside the the rim centre bore. I will nip out and measure the bore and hub and order a set up.

Brummie I did see the spacers on the website to enable the fitting of 304 mm discs. I've used CL pads in a couple of my race bikes a few years ago and the difference is night and day against the other race pads I used. I want to see if I can measure the run out and see which end needs replacing hopefully not the rears.

Thanks all
