[TR] Fwd: TR4A - Need Advice on Road Springs

[Jerry Van Vlack]

If you use the 1” shortened springs without spacers to regain original height with no shims on the lower A Arms you still can not get the proper camber. Been there and done that, only way was to somehow lengthen the upper A-arms. I have modified uppers which now allow adjustment out to get 1 degree negative camber. Never tried with spacers since I wanted the car lowered an inch.

RE: Adjusting front camber, can't you do the with the shims that mount between lower a-arms and the frame? 

Also agree the rear sounds like a shock problem.

I agree with Mark, focus on shocks and rear shock links especially. I once 
broke a rear shock link and the car bounced badly. I'd stay away from rear 
tube conversions, those upgraded rear lever shocks you're ordering will work 
just fine. If the new shocks don't fix the issues and you still want to 
replace springs I'd suggest buying the Goodparts set offered for a TR6 along 
with spacers to regain original height. If you decide to go lower you'll 
have front and rear camber issues to deal with. Goodparts rear trailing arm 
brackets will allow you to regain correct camber but the front will go to 
too much negative camber. The only way to correct the front is to somehow 
modify the upper A-arms or buy one of the English suppliers kits for upper 
A-arm adjustment. My guess is your springs are just fine and you'll find 
your problem is associated with the rear shocks and or shock links. 
Goodparts also makes an excellent replacement shock link kit too. Let us 
know how it works out.

All,

After almost eight years of driving bliss, with just under 18K miles, it's 
time to replace what I suspect are the original road springs.
The car has gotten way too bouncy, especially in the rear.  Take a curve on 
a rough road, and it rear steers something awful. losing its contact with 
the road, as if the spring is not forcing the wheel back down quickly 
enough.
As far as shocks go, I’ve got Spax adjustable up front, and just ordered 
some heavy duty Armstrongs from Apple Hydraulics for the rear.

I’ve gotten into some research, and everything seems to be pointing toward 
three grades of stiffness; original, uprated and competition.
I am leaning toward the “uprated” variety to stiffen the ride, but I want to 
keep stock height to not effect wheel camber.

Any experienced-based suggestions?

Thanks in advance.


Cheers,
