310mm front discs with early boxster calipers?

[-Alex-]

Here seems that with 312 rotor you can fit 16" wheel.

Does anyone have 16" porsche/audi rim that can measure area where caliper is? I'll check the space saver rim, it should be a littlebit slimmer from inside than regular 15" wheel.

Alex,
I would be concerned that the space saver rim is up to the job of full time duty. It was speed limited IIRC, that maybe related to the variation of wheels and tyres when used but I doubt whether Porsche will sanction it for full duty all round.

The 312mm disc will fit within the largest diameter of a 16" wheel with 37mm clearance for the caliper - thats seems a bit tight for a Brembo unit. Normally, the caliper sits closer to the nave of the wheel that is further narrowed by the rim well (~ 15mm) I had this problem when fitting the 928S4 caliper to the standard 15" wheel. It was correctly set for 944 N/A disc but fouled the wheel. Shaving the caliper didn't work well enough so I had to add spacers that are currentlyt 31mm, that meant wide wings and an increase in the front track to compensate for the rear track width etc etc etc.......

Clive, i will use it only at emergency, thats for i bought it. Also planning to use regular (skinny) tire on that space saver rim.


Wheels for everyday use will be 17" cup wheels. I have 3cm wider front fenders and 6cm wider rears.

Another possibility is to buy 996 or boxster spare tire, it is probably 16" or 17"

For occasional use then it will be used as intended. We have 4 steel 944 space saver wheels with 165x15 tyres. All have stickers to limit the speed to 60mph (96kph) but I am convinced that looking at the substantial construction that that limitation was for when it was used in conjunction with the standard wide/low profile alloy wheels and tyres. I intend to use these wheels for autotesting where they will help where less traction can be beneficial.

I have thought to buy that bigger spacesaver sparetire, lots of them available.


With 3,5 x 17 rim, i should not worry with 310mm brakes at front. Tire is skinny 105/90 R17, alternative size is 125/80 R17

Should fit great to under balljoint beetle hood =)

Now i am thinking to sell the existing 15" spacesaver rim:

Now i have that boxster / 996 spare, sure looks big and thin. Diameter is 630mm, but beetle original tire is same size, so it should fit to trunk.

Also have now steering rack kit from germany to my ball joint beetle.

Also designed hub with that wilwood hat, pic coming later.

Alex,

Many great gifts!
Could you tell me what this car is originally steering rack?

Thank's

Also designed hub with that wilwood hat and wilwood rotor, caliper at the pic is my own quick design, it is just for decoration purpose
