Hi.
recently i was thinking to upgrade my stock dual piston caliper G60 Girling brakes on the fron of my cab.
The big problem i am facing is the options for 4x108 bolt pattern. If i change hubs from s2 will be easier but one thing is for sure - I want to keep the 4x108 as i want to have the wheels that are on the car and keep them

I sourced cheap 1st gen Porsche Boxter calipers. So i am trying to find caliper bracket to fit them on the cab.
next is the rotor - here is a little bit easier since custom 2 part rotors are cheaply available and made to order. The Boxster has 2 types of front calipers 298mm rotors and 318mm. I prefder to go woth the 298 as it is smaller amd lighter but still good enough on Audi standarts.

My wheels are 17" 7j ET 37. Those should be big enough fpr the either rotor size as Boxster even uses 16". Only not sure for the ET but 37 should be ok?

If someone knows a way to upgade the brakes and keep my stock hubs PLEASE HELP. i will go other way if I know. There are some cars out there with 4x108 that has upgraded brakes but never heard how exactly. I have heard a8 rotors rs2 brackets and I searched for a week now for a topics over the forums but with no clear reaults
greatly apreciate any info

Georgi...you have a very ambitious project there and a good question. I would call 034 Motorsports and see if they have some clues..no doubt they have done big brakes on an Audi 90/Cabriolet in the past. Phone 877-591-9571

Over on Motorgeek: Are there any brake kits that retain 4x108? :: motorgeek.com

And maybe this will have some clues: UrS4.com Brakes

Search "boxster" over on Motorgeek under "brakes" and see if that helps?

Thanks Rusty
i will check with034 soon.
the rest of the info is super helpful but nothing specific...especially where and what caliper brackets to get..

I found that the Rs2 brackets will work with Porsche Boxster S calipers. But not sure for the caliper of the non S Boxster.
if someone know if the Box S calipers will fit wheels with offset 37?
