Binding calliper on one side?
PH2 172
Haven`t you recently taken the AP coilovers off?
Was this occurring with these or their replacements?

Indeed, got ASTs on now. Don’t think it’s related to them!
PH2 172
It was doing it before you fitted them then?
As a matter of interest have you had the car corner weighted with the AST`s on?
You've had it aligned though right?
But did you check the caliper is floating freely?

FFS, Graham is no novice.

Read his threads?

So you think you are clever?
This car is running an experimental roll centre & bump steer kit.
If the wishbones hang at an negative angle, fully loaded, braking will induce additional toe in
Listening to that Steve its even more likely to be a bush as loaded in that way will give them a tough time.
Shame they cant be rose jointed , but id at least run solid nylon if possible

The wishbones were actually replaced with new OE items not long ago, but fitting black powerflex would be an improvement.
There was also a problem with the thrust line/rear toe that I cannot see has ever been addressed.
Needs fully flat floor and geo first ... no guessing
Then see where it is but i still recon a wishbone is moving , no other way really to happen unless the rack is goosed

Yeah all working well and lubed up. They were refurbed not too long ago.
I’m a good bluffer :smile:
I barely know my own. Soft office hands.
All the bushes are good. Was the first thing that came to mind!
Checked the tracking again last night. I strung the car on Saturday and did it with a 0.5mm accuracy ruler. Yesterday I did it with vernier calipers which read to 0.01 mm. It only needed some small adjustments which I did on turn plates. There is some improvement but by no means is it gone.
Correct though there is some rear thrust angle which hasn’t been resolved ever. It’s static though.
Tracking results from last night.
Only thing i could think may affect it on both acceleration and braking would be a loose top mount causing a caster or camber change.
Would be rare as i would expect a significant knock

I'm almost 100% sure this is driveshaft/gearbox related.
I can't just swap back to the APs back on because they're on different hub spacing and it's a HUGE pain to change between the two. Look back at my recent power to weight shootout this looks to be quite a similar issue to the one I had on the dyno where it slowed down much faster on the right hand side than the left. I'll have a good look over that side but there is honestly nothing shouting out to me. Will have a looky look tomorrow.

What tyres are you running g?
'10 Clio200
engine mounts or tyre related. The latter easier to check by swapping tyres :wink:
My focus rs mk1 had terrible pull issues and was the gearbox mount
