Rear suspension - Keep or change the springs Options

[PaIsa]

Yesterday I was able to take out the rear shocks & spring as well as one of the rear control arms but breaking 2 bolts in the process! Will find solution for this in the coming days

When I disassemble the shock & spring I found out that I have Weltmeister 180 spring with KYB shock. I plan on replacing the KYB but don't know what to think about the spring. I thought that 100lbs spring was the stock on these cars.

The ride was not unpleasant with the current set up so I would consider keeping them. Any advice anyone?

The car is a 1972 with a 1.7L engine.

Thanks

There is no one size fits all answer.

It depends on what you want. Do you want a plush, soft ride or do you want crisp, responsive handling? Street use, auto cross, or track use?

Do you have anti-roll bars and what size? Front bar only, rear bar only, or both front and rear anti roll bars?

What front torsion bars do you have? Front bar only or both front and rear anti roll bars?

What tires are on the car?

Do you prefer a vehicle that oversteers (like an early 911) or do you prefer the safety of understeer (typical modern vehicle).

This book is a must read if you really want to set up a vehicle to your specific liking.
