Red face 67 Impala SS suspension help,

Hi Guys, me again

so i have decided to go with the cheaper option (for now) and spend more money on the body and motor ... i will upgrade or do all the bushing / rubbers on my suspension , lower the car with a 2'' drop spindle and a set of springs and shorter shocks for now,

My question is what is the best bushing kits for street use (weekend car) and if you can help with a link , im looking to order from https://www.classicindustries.com/sh.../impala/parts/

i need to do my complete front and rear suspension rubbers and bushes ,

I'm a Polyurethane guy. They are a little stiffer than stock, but these cars float anyway.

I would also look at newer lower ball joints while replacing the control arm bushings. These are hard to get to later if you have to replace them. The uppers are easier to swap out at a later date if you have too.

I'm a little surprised that being from Michigan that you prefer the polyurethane bushings. In our areas of midwest with rougher roads with expansion strips and more settling I found the poly bushings to be a bit too harsh for me. Perfect for a flat road, but at speed, the typical roadway transitions and expansion strips just take a toll on you after awhile.

I don't think I'm much help on this thread anyway. Not sure Classic Industries sells everything I ended up with on my supension.

I can add that some consideration should be given to replacing the body mounts as well. At least crawl around under your ride and check out their condition visually to ensure they aren't badly deteriorated.

I would choose:
Rubber --> I've seen polyurethane damage stock suspension.
Ball joints, bushings, tierods etc. --> Buy quality American made parts. I recommend MOOG.
Springs --> aftermarket springs are too stiff and make the car sit too high. Re-use originals, if possible.

I've done my 67 with Moog (no longer made in USA) front and back. Very happy with results. I have polyurethane on my Cutlass and I'm never running poly again.

I'm not a big believer in putting rubber bands on rims and calling them tires either. A 15" rim with a tall sidewall helps to soften up the harsh roads. You start sticking 20" rims on a car and your sidewalls are so short that they have to either make them really stiff or you have to run really high pressure in them to keep from bouncing on the rims. In my full size truck with 20" rims I have enough side wall to run a 35 PSI and the ride is great, but my oil change shop likes to pump them up to 40 PSI and then she bounces around like a 3/4 ton truck instead of the 1/2 ton Cadillac she rides like normally.

As Michigan guy and an old school guy, I agree with you 100%.
