VWR brakes, very disappointed, but hoping to feel better !

[Carrera2RS]

I run 35-40mm lower at the rear and 20mm at the front. I have a lot of extra track...

Wheels ET45 8x18 so the outer edge is 12mm a side, plus the TT bottom arms which add track in order to add camber, this adds a further 12mm at the hub centre and 6mm at the top arch.

So at the arch lip nearly 18mm additionally track per side, so total track increase over 36mm at the arch, nearer 48mm at the hub and more again at the bottom of the wheel as I run 2.15 degrees negative camber at the font. I have not had one touch of the arch since, I have been cornering hard over some very undulating surfaces and it's been prefect

Can you stop posting photos of your car please.... It's making me jealous.

Does the camber on the front make a lot of difference?

[Carrera2RS]

Sorry for all the pictures 

Yep the camber (and I suspect track) makes a marked difference. I explored the chassis balance at much higher speeds than your big roundabout speeds to see how the balance might be at much higher speed. It was remarkable and was still very planted and when I did feel the weight transfer uncomfortably load up the rear and hinted at braking away, a touch more throttle and it was back to neutral. Turn in is excellent with front camber. Understeer is virtually a thing of the past

Carrera2RS I have a pretty similar setup (TT arms, lower suspension) but have both smaller offset wheels and larger offset wheels. With 8inch (width) rims and ET50 I have rubbing on Nurburgring and there is not one thing I can do about it (except to buy some wider fenders). With the ET40 wheels I do not dare going to Nurburgring. I am also planning to buy some TD Pro Race 1.2 (17 inch though) and I have a question: when you mean there is no rubbing did you include very bumpy tracks like the Nurburgring Nordscheife?

[Carrera2RS]

I have not driven on track, but there were a number of very unpleasant bumps that would clip the inner fender before the arches were modified, now I have yet to have any problems at all.

Some bumps I have been over nearly bottom the suspension at speed, so I do believe the problem is now removed. Even 3 people up and pushing on over poor roads, no problem.

OFFTOPIC. Well... I hope you are right . I personally doubt it, but a trip to Nurburgring will prove one of us wrong (I will buy the wider fenders to get rid of this issue). The immense differences in elevation and 90+ mph will make the car behave differently than on a normal road even if the car is loaded.

Oh another thought, I am not sure if Simpson Motorsport 'pulled' the arches a little, I did mention that loosening fender mounts and a little adjusting then re tightening had also been mentioned.

The inner lip is rolled back and the inner arch moved upwards when they did this, not just bolt removed. I take your point, there is a real 'dipper' on one of my regular trips, when I had my E92 M3 I would hit the front spoiler on some occasions. This was a slow down point for me as it can throw the car around, even this was okay at speed and getting thrown around

I guess the answer might be very different if you get corner loading and a real awkward dip/bump. I'd like to try and see, but for a road car it has not been an issue so far (1,000 miles or so)

Thanking you mate ! Sounds like i might need to get my arches modded or new wings with a bit of clearance !
