Tried a quick search but didnt come up with anything, probably is something already but its a difficult question to search for!
Bassically i want to know how much stiffer, or firmer my AE86 will be if i change from the stock Aus spec springs ,to 8 or 6kg front springs and 6 or 4kg rears.
I already have adjustable dampners front and rear, and even on the softest setting the car is fairly stiff on the road. You can really feel any small bumps on the road!
The car is a daily driver, so i dont really want it to be to much firmer on the road, even though it would be more fun on the twisty runs!
I currently have 16" rims on the car, however if i change the springs i might go down to 15"s, will this effect ride stiffness at all?
Any advice would be appreciated.
Thanks
