Gav, that looks much better, it even looks like it will handle now.
I have been playing with mine recently.
I have popped some adj. top mounts on I got off Theo which UweM3 made on here. 3deg. neg camber on the front
I have put some eccentric trailing arm bushes on the back to pull the rear wheels more upright and run 35mm H&R springs which give it a nose down stance similar to yours.
A slightly soft setup is always good as the road isnt a billiard table.

I would say 9's are too wide for your application. I know they are 15" but a set of std BBS with some 205/50's would make a difference to what you have on atm.

Funny thig is , its now closer to standard spec than it was before.
May put some sticky rubber on my spare BBS for driving and keep the BKs for gaying,

Are you sure you want less camber on the rear? it will help with straight traction but wont you lose some high speed corner rear grip?

Adj top mounts :drool:

Softer seems to be the way to go, far more forgiving if you hit rough tarmac on a corner and better wet weather grip.

Brakes next.... winkeye

I guess the m52 is in your lazur shell now, so have the shocks, springs & arb's bedded in nicely now? It was fresh out of the box as I last witnessed..

an iS takes more effort to keep pace, but it's huge fun on short runs. The 325 feels like an agile express train. Much more relaxing as the torque allows your right foot to do more of the talking - you can drive in a hurry for 40 miles, get out and feel like you've just been around the corner.

Your 4 pot Bob is a different ball game..
Yes it's in the lazur now, got some wider rubber for it too lazy power :) all settled and all cambered up well

Gav- I have corrected it back to standard being 35mm lower it increased and now I have decreased it. technically I have more grip as I have less camber on the rear, I think I have .7deg on the rear now

Edit.. I have been playing with my 16" and 308mm discs, 540 calipers ftw :)

The budget to breath on my brakes wont go to 540 spec , which is a shame.
Just fancy disks n pads with nice fluid.

Does that set up fit in 16s?

With adjustable top mounts doesn't the spring of the strut come pretty close to hitting the tower?

Annoyingly on 205's you really need coilovers before you can make the most of the adjustable top mounts.

The off set top mounts on simons are well over with a normal set up, shouldn't think the adjustable ones will be far different?

Also, at least on a 205 you only need 2 coilovers, unless you lose the torsion bar set up and go all out.

It's not THAT expensive I think I will manage to get in under £150.
They do fit under 16's I'm just uploading some pics now.

Jon, I cant say I have looked but I have not had any interferance at all so far?

edit.. uploaded my pics now..
trial fit together I need to mod my spacing bracket as I had made it for a 312mm setup but figured that it was all a bit too tight! It could work though looking at it now..

and the space between my bolts and the caliper. I have messed about with this caliper in a previous attempt at fitting without some nessarcery parts so will be replacing it when I next go the breakers

Happy days. You'd know straight away if they rubbed I suspect... 205 tolerances are shite at the best of times. :? Plus each car is a little bit different, depending what day of the week it was made on! :o

Don't get me started on torsion bars/beams! :)

I'm not sure yet I'll be honest I think the 750i M/C will be in contention when I get there there is a lot of fluid to move in those calipers

I was thinking a 944 one , im told they fit with M50/52 and maybe the m/c can be adapted?

ooooh sorry I read wrong what a spaz. I thought you said M/C.
I'm not sure on servo yet I've got a S50b32 plenum to clear so maybe a golf or clio one? I suppose what I can find that fits I will go for a walk about the scrap yard at some point might try something remote?
