Looking at set of cup 2 wheels, et 55 17x7 and 17x9. I want the fronts to fit under the stock fenders. Using a 944 brakes, im thinking of using this method

#1) Take the whole 944 spindle. This only applies to 1303’s. The 944 spindle will interchange with your 1303 spindle. This applies to the early 944 NA spindles (rotor mounted to hub from behind). The stock 1303 strut (and early 944) has a 20mm wide tang and 58mm hole pitch. The later (86+) 944 spindles have a 18mm tang width and 63mm hole pitch, and therefore will not be compatible with the 1303 struts.You will need special lower ball joints (17mm for 944 vs 15mm for stock 1303) available from european sources. If you have a 1302, then change your suspension (struts, spindles, lower control arms) to 1303 components. By using the 944 spindles, you have all required mounting points for the calipers/hubs etc. Your dub will be 944 from the spindle out. There may be an issue with the speedometer cable, as some 944 spindles are not machined for the cable. The tie rod mounting location may need reversing, easy to do with the current availability of the ‘bump-steer’ bushings. Also the tie-rod will have to be longer since the 944 steering arm on the spindle is straight, whereas the 1303 steering arm curves in towards the center of the car. The 1302/1303 tie rod ends will work with the 944 spindles. Overall, you will have to source everything from a 944, spindle out to perform this conversion. There is an offset increase of about 20mm (?) per side. The 944 spindle will also give you alot of positive camber, but you maybe able to remedy this situation with aftermarket camber adjustment bolt that afford greater adjustment.

Being like this, 20mm offset per side added. Could the wheels still fit being et 55? I dont want to use wider fenders, and I plan on running somhting like this
