Here's what I did on my 1975 GT clone.
911 3 inch strut housings with Boge inserts.
Kept the 914 A-arms and torsion bars.
911 M calipers on all four corners with 911 E-brake.
19MM adjustable front sway bar no rear bar.
Elephant Racing polybronze bushings all the way around.
Lemfoerder turbo tie rod ends.
Koni rear shocks with 140 lb. springs. Will do Bilsteins in the future with adjustable spring perches.
19mm master cylinder.
Had the car aligned and corner balanced and she's a go kart.
I have metal flares with 7 + 8 inch Fuchs with 205/55 + 245/45 tires all being pushed by a 911SC 3.0 with Weber carbs.........2100 lbs. of fun
