Porsche part swapping
 

Got a question about the 944 alu. trailing arms.

I've got the early 86 alu. arms (the ones with a bump stop) and was wondering if it's possible to swap out the stubaxle, rotor, e-brake hardware & whatnot, for the late model or turbo high offset parts to widen the rear track. Another guy here is doing the same swap but under a ghia so he's limited on width, and i'd like the wider track to help fill my fenders a bit :)

as far as i'm aware the rotor stub axle and e-brake hardware will swap, but the turbo 4 pot calipers have a different bolt pattern correct? same goes for the front 86 944 spindles, different bolt pattern from the turbo 4 pots?

It's not the stub axle and hub that widen the track, it's the trailing arm so you'd have to change to an 87-up arm and yes you are correct the spindle's bolt pattern for the caliper is 76mm for NA and 94mm for the turbo.
