I have an 87 Carrera. It is my understanding that the offsets for a 17 inch wheel are the following

Front - 8", 23.3 mm
Rear - 9", 15 mm.

I just spoke to a Fikse rep. He said their specs show the following offsets

Front 31 mm
Rear 18 mm

Who is correct?

In addition, I upgraded to 930 brakes. Does that make any difference.

Thanks

the 23 for fronts and 15 mm are what will fit 16" fuchs. The 31 mm offset will give you a little more clearance in the front - you may not have to roll the lips - Most with 8" x 16 fuchs have to roll the lips in the front.

BTW the 23.3 is the offset for the 944 turbo 8" x 16 wheel that you can put on the front of a 911.

The offsets for 15" or 16" Fuchs is as follows

• <font size="2" face="Verdana,Tahoma,Helvetica">+23.3mm for 911 7s or for 944 7s or for 944 8s (front 911 use)</font></li>
• <font size="2" face="Verdana,Tahoma,Helvetica">+10.6 for 911 8s (rear 911 use)</font></li>
• <font size="2" face="Verdana,Tahoma,Helvetica">+15mm for 930 9s (rear 911 use)</font></li>

<font size="2" face="Verdana,Tahoma,Helvetica">Aftermarkets have varied proprietary o/s
</font>

• <font size="2" face="Verdana,Tahoma,Helvetica">8" Fikse for 911 front use is either +31.3 or +18.6 mm o/s +31.6 is the best fit often w/ a 5-7mm spacer</font></li>
• <font size="2" face="Verdana,Tahoma,Helvetica">Fikse 9s come in the same o/s's but the +18.6 is best for rear use</font></li>

<font size="2" face="Verdana,Tahoma,Helvetica">Other manufacturers have their own o/s but for 911 use 8" fronts need +23.3 to +27mm or so and 9" rears need +15 to +19 or so
Wider wheels of course would warrent different o/s
I bought Kinesis because their o/s were better(IMO) for SC/Carrera use +25mm 8" front and +19mm 9.5" rear

The higher the +o/s # the further inboard the wheel will be.
