My story so far....
I have waited for a long time, I cant remember how long but months to get a set from VWR, they were delivered to Simpson Motorsport.
I took today off to get them fitted, not a good start, no instructions, a chip on the paint, no washers where Simpson say there should be. The bolts not plated, but.....
No matter they are cheaper than AP and the guys know what they are doing, in the bays sit, 3 BMW CSL's, two Brit cars, two Z4s with cages, buckets and track tyres and two F40's and my Golf ! All others having much more serious stuff undertaken, I am in safe hands.
Problem 1. The calipers were built upside down ! The piston order was wrong, Simpson said this way round could cause binding. Again no matter simply dissasemble pipes and swap round.
Problem 2. They were built an and overtightened assembled with no copper slip, but the guys did sort one caliper in reediness for fitment
Problem 3. They don't fit ! They hit the backplate, no instructions, so backplate off. They also hit the bottom ball joint.
Problem 4. At each interval Simpson phone to let them know about the assembly issue in case they are sent out and installed by less experienced people, to find if the backplates should be removed, to discuss the clearance problem, they are racing.......no one home that can help.
Quick measurements highlight the problem, the inner face of the brake disc sits 8mm further in than stock, this is about the total clearance. If they did clear then the caliper did not appear to mount centrally around the disc.
Possibly incorrect machining of the bells I have waited weeks for. I have paid Simpson for the brakes and work as it is not there problem and they have paid VWR
£110 plus vat in labour a day waisted, no brakes and no answers, VERY UNIMPRESSED
