Hi everyone: MartinsVette2007-10-27 21:46:22

your thinking is good Martin. I've been running th trw style 340# on 2 cars ( because I found them at Muskegon Brake for $279) and the 1st one I bought felt great to me. Just a little on the performance side (stiff) less weight transfer coming off the line . I love it  personally, and I've heard others say they were just a little stiff for them. Any spring you get will be an improvement.

I have the VBP composite 330# on the rear of my 72 and love the ride. I also have the front mono leaf, did away with the coils and now I can change height and ride firmness with very little effort.

Wow. Very nice Fred. A lot of us are interested in that conversion. Is that also a composite ? Where did you get it ?

  The TRW Style is what GM used on the 81 and 82's. The Straight Ones generaly come from VB&P.  The way they make them is to make three at a Time in there Mold and then When they are Cured they just Cut them to width on a Table Saw.  I put a 330 on my 80' about 20 Years ago when they First Came out and it has Held up Great. The big Problem is Exhaust Heat they don't like it.  If Your exhaust dosn't allready have a Heat Sheild where it passes under the Spring You should Fab one just a Small Sheetmetal one works well.

The #315 will ride a little softer than the #330.

I just replaced mine with the TRW and I am very happy with it. They do seem to raise the rear end a little even with the 8" bolts that come with the install kit. They also come with the exhaust shield and new bushingsRedwingvette2007-10-29 12:37:31

Thanks for the input guys. 

I unbolted the rear muffler clamps and the exhaust hung down enough to get the spring out/in. I had the jackstands placed at the back of the doors and I took the drivers side tire off for extra room. Took me about an hour and a half.

Great,

 Cosidering that Your Car is an 80' (like Mine) It was the First Year of the Dana 44 Aluminum Rear End. It Uses a Diffrent Spring Perch than the previous design and its been so long since I first Installed my original I can't remember if You need to replace the Clamping Plate that Holds it or Not. VB&P might send one with thre Spring and I have no know idea of how TRW dose it. Whenever You Order it be sure to Ask. As Most Springs Sold are for 63' to 79"s ,and 81'to 82's allready had the Composite Spring it Leaves the 80' in the Gray Area. Somebody Here must of run into this issue in the 20 Plus Years since I did Mine and they probably have better Memory. Richard.....

 I've replaced my '81 and the '78. Both with the TRW style. Both came complete with all you need. Just be careful compressing each spring end to start the castle nuts.

  Jimmy,  Sorry it took so long to answer, I bought the set from Vette Brakes VBP, they run sales every now and then. The front is a fiberglass mono that can be ajusted very easy to firm up the ride or soften it up. The set is a bolt in, and it was the easiest thing I have done to the car...less than three hours to install. You can buy just the spring kit or the spring and lower A arms and last is upper and lower A arms. Unless your upper arms are bad dont waste the money, just get the lower A arms with the spring. A arms are powder coated and look really good.

I got the TRW 340# and love it.  Our roads are the worst and this spring really helps smooth out the ride.

Thanks a lot guys!  I really appreciate the feed back.
