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.

http://images.thesamba.com/vw/gallery/pix/497254.jpg

Last summer:
17x7et55 (205/40) and 17x8.5et55(235/45) techno-twists. On 944NA brakes, used 12mm rear spacer.
http://images.thesamba.com/vw/gallery/pix/390763.jpg
http://images.thesamba.com/vw/gallery/pix/497255.jpg

This summer: 16x6et50, 16x7et40 boxster split stars, with 205/40F and 225/50R on 964 C2 brakes.
http://images.thesamba.com/vw/gallery/pix/497256.jpg

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.

Steve C November 15th 2008 17:40

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

Lanner

Steve C November 16th 2008 04:44

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.

Hi James

He just got his licence on November 1st, I have a 1776 ready to go in when he has a bit more experience, then some dual 40mm Webbers.

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 :D ):

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

Wally November 16th 2008 10:18

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

Wally November 17th 2008 03:14

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.

Steve
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 :D

Wally, why not just add a bias valve to the rear line or a balance bar m/c's that would retain all you have achieved and allow you to dial in the correct bias?

evilC

Wally November 17th 2008 10:42

That was my second thought Steve ;)
Its just that I have noticed that when fully loaded with family and luggage (i.e. dog) and traveling at speed, braking to a full stop does suffer, which is mainly due to the front brakes (they look just like the orginal cast iron ones, but are only one size bigger) with the non-vented disk.
Therefore I still hope to come up with a solution to mount a nice alu Brembo to the front. Problem there is the spindle, its different from a type 1 so a 944 adapter bearing is maybe not possible...but let me worry 'bout that for a while ;)

evilC November 18th 2008 09:05

Wally,

Why not fit the 944 struts c/w discs, the early ones are a straight replacement and even have the speedo cable hole?

evilC

Wally November 18th 2008 09:57

Not a straight replacement on a 412

Wally, they are the same bearings as BJ/SB. I'd like to come up with something if you're up for it? Probably could do a 996 bolt on kit....:)

Yes the wheel bearings are the same, but they are wider apart on a 412 than on a bug (any year).... I have the adapter parts to press in, but I am not sure the bearing houses would have enough material left in the 944 hub to reside in...

Lanner, if you could make me something, I would definately be up for it, spindle/hub wise or caster adjustment ;)
You know the top strut bearings are the same in my 412 as in my late 1303 beetle and I need the extra caster on both. So an adjustable caster top bearing plate is still on top of my list. Caster I have now is between 1 and 2 degrees and needs to to 6-8 or so for optimum straight line high speed stability. I already have the Topline caster+ sway-bar bushings, but its not enough. Mayby because of my M030 front spindles but I dunno.

Untill I have some top strut caster-adjustment parts, I don't dare go any faster than 120 mph or so....
The lowered 412 has the same problem. So two sets of these could make this all a happy world :rolleyes:

Well, you can't blame a guy for trying right? (I know you have other engagements ;) )

Thanks,
Walter

Wally,

No worries, I'm on the project. But I'm in the process of moving and then off for almost a month. So it'll be into the new year before I have anything concrete to show. Also, not sure if I can get that much adjustment out of them. Will have to get out the slide rule and figure it out :-P. Are your cars sleeping for the winter?

In the interim, I could probably come up with a static upper mount with spherical bearing. No adjustment, but fixed at a certain positive caster. Quick, dirty (and probably cheap). You can guinea pig them for me :)

If more movement is neccesary for them to work (increase caster by say at least 5 degrees or so), I would not mind filing out the upper strut openings in the body.

The 1303 is, as I always seem to come up with new plans that require engine and trans to be removed from the 03... but the 412 is my daily driver.

That would be a very good idea! I could do that easily in a weekend and have the car realigned with the extra caster afterwards.
Cool! if you could make that happen, pls do so. The details we can discuss by PM or mail ;)

Tnx in advance Lanner!

Pictured here are ROH 16 x 7" and 16 x 8" rims that were made in Australia. These are on my '73 Super with 924/944 lowering springs, probably too stiff for the street but I'll see what I want to do after autocrossing the car. They weigh:

16 x 7" 19lbs.
16 x 8" 22.5lbs.

I was doing a test fit here, currently I have 928S rims on the car. Will be getting widened fenders at some point, etc.

Super old thread, but still info to know.

I picked up a set of original phone dials in the early offset (ET23.3). I'm running n/a 944 front discs and coil overs with 2.5 inch springs. Where would the phone dials foul the car? Total back spacing is 112.2mm. Seems like it would fit.
