 Figured I would share a few pics of my 5 lug swap on my 75. I used 3.5 spaced 911 struts and Boxster calipers all around using the Rebel Racing kit. Wheels are 16x6 and 16X7 fuchs with 195/55/16s on all 4. I originally had 911 wheels all the way around but the rears had a slight interference with the calipers. Rather than use spacers I switched to 951 rears and the fit is great.  |

Justin - nice job, the car looks great!
Just FYI: there is a subtle thing with Boxster calipers on 911 or 914-6 struts. Because the 911 strut places the caliper ahead of the wheel (and the Boxster has it behind), you end up fitting the FR caliper to the FL strut and vice versa. This works fine, but it does mean the offset piston sizes in the caliper are now reversed, with respect to rotor direction. Why the offset piston sizes? Complicated, but the Fred Puhn braking book talks to the issue. There may be better explanations out there. You can easily fix this by inverting the link pipe and bleeders between the two calipers, then swapping the sides. Which you really don't want to do right now, as you've just bolted them to the car and bled the brakes...! The big question is: does this really make a difference? I have no real evidence to prove it one way or the other. I can imagine it makes a difference to pad wear long term - but do we care? Either way, I have the same front strut / caliper set up and my car, and very happy with the results. Again, car looks much better!! - Tony |
