I'll bite...

My 1302 - Boxster S brakes all around, with 944 steel arm rear setup (+22mm per side). Modified 944 hubs in the front for beetle bearings (+15mm per side). 17x7et55 cup II's in the front (205/50), 17x8et70 Cup II's in the back (225/45). Topline struts (old style) with honda coil conversion. Stock fenders, fits lovely.

Thanks Lanner, using this thread as a FAQ and if everyone (tried and true) can post their results it would be a valuable resource.

No worries Superman. This is a great sticky. Here's a setup I did last winter (Nelson's Vert):

1302 Vert. Bugpack adjustable struts, Honda coils. 944Turbo front brakes, with modified 944 hubs in the front for beetle bearings (+12mm per side). 944 steel arm rear setup (+22mm per side). 16x6et52 964 starfish wheels in the front (205/50), 16x8et52 964 starfish wheels in the back (225/50, IIRC). Stock fenders, Everything fits well, but the 8's in the back don't work (rubs fender) in that offset. Will be changing to 7et52's and everything will be butter.

One more (Carbo's Rag)

55 Rag. 3" narrowed beam (BJ). 944NA front brakes, with modified 944 hubs in the front for beetle bearings (+15mm per side), on welded dropped spindles. 944 steel arm rear setup with 944NA brakes (+22mm per side) modified for long swingaxle tubes. 17x7et55 Cup II's wheels in the front (205/40), 17x7et55 Cup II"s wheels in the back (205/50). Stock fenders. Everything fits well, but we had issues with inner front fender clearance. Added 20mm fronts spacers with long studs (OEM, from 944 rear) and everything is great. In retrospec, should have started with a less narrowed beam. 1.5" narrowed beam would be perfect.

My Bus. This thing has gone through many wheel/brake setups.
All have these common elements, 4.75" narrowed beam , 3.5" spindles, IRS conversion with wagenswest kit using 944 steel arms.

First off: 944NA brakes, 15x6et36 cookies, 175/55F 185/65R.



Last summer:
17x7et55 (205/40) and 17x8.5et55(235/45) techno-twists. On 944NA brakes, used 12mm rear spacer.



This summer: 16x6et50, 16x7et40 boxster split stars, with 205/40F and 225/50R on 964 C2 brakes.


I also had 17x7et55 and 17x9et55 Cup II's on the bus with the 944NA brakes, but can't find any pics. The rear was a SQUEEZE, but it fit.

Hi

Not Porsche wheels, but the offset and size are Porsche like.

17x7 ET 55 (factory Subaru BBS), on a 2 bolt 1303. Front fit nice with narrow coils, rear needed to go steel 944 arms & brakes, fit really well.

Steve

Steve, Looks killer. You remachined the rear 944 brakes for 5-100? What brakes in the front?

Hi Lanner

Thanks, it is 5x100 now. This is my sometimes daily driver and sons 1st car until I finish my other 1303.

I was able to score for the rear a pair of twin piston alloy Brembos from a later 911, these have 42mm pistons. On the front I'm using stock bug rotors with early Type 3 calipers, these also have 42 mm pistons. Its very slightly biased to the rear, I'm fitting a bias valve soon.

Steve

IIRC, the C2 rear 2-pot Brembos were 44mm? Anyways, I really love those calipers!
Work great on the rear of my VW412, speaking of which (see the bridge I'am making ):




Porsche ClassicSport I (BBS made) 7x17 ET55 and 8,5x17 ET52 with 195/45(in the pic still 205/50) and 225/45 rear.
Front calipers are BMW 320, 48mm cups. Adapter plate for the off-set and stud-adaptment

The bug has the same wheels, but in 18" form 7,5J and 9J wide with 245/35 and 225/35 (now 225/40) semi-slick like tires.
993 rear calipers on the rear, GT2 rear ones on the front. Alu wide rear alu arms, front has 18mm 944 spacers with the original long studs, which gives an amazing original steering circle (which is relatively small for a 1303). Original size (wide) springs up front. Widenend fenders from Kerscher.

Hi Wally

I must have got something wrong in the measuring.

They are an amazing calliper, very light. Would they fit on the front of a 944 setup? On my car they work very well with the stock 19mm M/C.

So your running 48 mm front callipers are you running the stock M/C?

Steve

No, the bolt spacing of the rear of a 944 (all models) is 94mm IIRC and front 944 is 76mm bolt spacing. Also to remember they are for a 24mm disk; not many front disks are 24mm but you could make s/th work I' am sure.

Yes, with the stock front solid disk. Very hard/high pedal. Really pulls it to the ground on all 4 corners simultaneously. Its an amazing sensation as the car doesn't dive anymore under braking because of that. I do encounter the rear to lock up first in some extreme situaties, which isn't good, so I want to install something porsche/brembo in the front as well one of these days. A bigger disk will probably avoid fade and bite a bit harder/longer so balance will be a tad less agressive. Though I really like how it brakes now, even with the knowledge it could/will lock up in the rear in the end.. I know I' am weird/suicidal
