[TR] TR4A springs

Fri Jun 9 06:50:08 MDT 2017

Dave, 
Good to hear from you. Was hoping to see you again at Blackhawk but looks like you can’t make it. Maybe next years event wherever that is.
My upper control arms were modified by a local race shop made adjustable using Heim Joints. He has done several sets over the last few years for many of the Pittsburgh folks.

John, 
Dave’s suggestion is a good one for the adjustable upper control arms should you go that way. Someone else mentioned that after buying what was advertised as original springs he returned them. That reminded me of my own experience with some aftermarket springs as I had the same result with some rear springs that I bought a long time ago.
In your original post you did not mention why you want to replace your original springs. Lets start there. What are you trying to accomplish? It just might be there is nothing wrong with your OE springs. In my case I wanted to lower the car, but the OE springs were fine after almost 50 years. I may still have those springs hanging around and if I do I’d send them to you for the price of the postage if you really need to replace yours.

So let’s keep discussing this and I’ll help you get to a conclusion. I’ve included a photo of my car with the 1” lower springs as a reference for how a TR4A looks when lowered a bit.

Hi Jerry.
John, if you do lower the car with springs and the camber needs to be adjusted beyond the factory capabilities, RevingtonTR in the UK makes an adjustable upper fulcrum pin that allows much adjustment.  You would not have to shorten the upper control arms.
I have the kit on my TR3.  It's a very good product.
I saw a RevingtonTR kit on eBay recently, so check there first if it interests you.
Also, if you'd like for information about RevingtonTR, check out their website.  They sell some really neat performance parts. 

Good luck,
Dave H.

I use the GoodParts 1" lower springs front and back. While the ride is 
acceptable to me other may say differently, a smooth ride is not what I've 
ever experienced in a TR, but that's OK with me. Best ride would be stock 
springs. If you do decide to go with the lower springs keep in mind you will 
need to do some modification to the upper front control arms to get the 
correct front camber adjustment. With no shims on the bottom I had too much 
positive camber, I needed to shorten the upper control  arms to get a bit of 
negative camber.

Am replacing the original springs on my TR4A.  Looking at what's available, 
one vendor is selling a 4 spring "high performance" kit that also lowers 
ride height about an inch.  Is anyone using these springs?  Also, there is a 
big difference in price for front and rear pairs of stock type springs from 
different vendors.  Would greatly appreciate any comments, recommendations, 
etc. from anyone with experience with new springs.  BTW, I'm looking for the 
best ride, am not competing.
