Pulling G's

Hello all,

I own a 64 Impala coupe and I have a question that could hopefully someone with first hand knowledge could answer .
What kind of performance can I expect from Global West U/L control arms, 1- 1/4" sway bar front and Global West 4 link in the rear? BTW, I also have 2" drop spindles and Global West drop springs front and rear. The last time that I drove it, the whole suspension was pretty worn, so I don't have a good reference point.

Make sure you do all new steering parts, too. The performance will be directly related to the tires. With tall, skinny tires (stock), it will be decent. With low profile, wide, sticky tires, it will be absolutely eye opening. My 65 is stock, and I like to cruise. However, my 95 is lowered, has custom arms, Bilstein shocks, big sway bars, and 18x8.5/18x10 wheels with sticky 275 40 18/295 35 18s. It sees duty on the street, but has been on drag strips, autocross, and road course.

Two doors, four doors, wagons, and ragtops.

I used Global West polyurethane bushings and front suspension parts and Hotchkiss' largest sway bar and it made my former marshmallow tough stock suspension handle more like a slot car. It went where I pointed it and cornered without any drama other than everything in the car sliding from one side to the other if not belted in place. This was on a mid eighties B-body which already had HD Police suspension under it (which is much stouter than stock). So yes it will improve handling.

Like Dave, I also used poly bushings in my custom arms (and on the sway bar links).

The Global West Del-a-lum bushings are amazing. Poly bushings are great as well. I prefer spherical if you can handle the road noise

I don't have any first hand experience with classic Impala's yet (going to be installing a RideTech coilover suspension as soon as my backordered parts arrive).

I do have experience with newer Camaros and the difference suspension makes. I had a stock 93 Camaro Z28 (100k + miles) that I installed all poly bushings and upgraded the stock a-arms, LCAs and shocks.

I took it to Summit Point, West Virginia and had an instructor friend of mine put the car through some heavy paces. Prior to the modifications, the car would pull between .63-.68 g's on the skid pad. Post modifications with some decent Yokohama street tires the car pulled well over 1.2 g's without any complaints and would no doubt be much better with drag radials/slicks.

That's a pretty big improvement for the amount of money invested, and you will no doubt see similar gains upgrading the impala suspension. GL!
