Jeff Donner Posted January 16, 2020 Share Posted January 16, 2020 First of all new to site and new 64 Riviera owner. Can I install a slightly larger rear coil 1” without changing anything else. “Should I”? Link to comment Share on other sites More sharing options...
jan arnett (2) Posted January 16, 2020 Share Posted January 16, 2020 You should probably post this in the Buick section but what are you trying to achieve with this change. 1 Link to comment Share on other sites More sharing options...
FLYER15015 Posted January 16, 2020 Share Posted January 16, 2020 Short answer is yes you can. I changed the rears on my '65 Riv to "station wagon" coils and got about 1.5" at the rear wheel well, and about 2.5 lift at the rear bumper. That changed the caster but a new alignment fixed that. Much better stance and did not notice a harsher ride. Mike in Colorado Link to comment Share on other sites More sharing options...
