I've recently picked up a 1990 EF Si for a project STS car. I'd like to know the corner weight of the car, so to determine some good spring rates. I'm guessing the rear is around 400 lb/side. And the front 650 lb/side. Any specs. Or tips for an STS car.

 

When I corner weighted a slightly stripped 88 HF these were the results:

Total weight: 1775
LF: 577 RF: 587
LR: 313 RR: 298

Hope this helps some!
