Ok I know most of you are better at wrenching then I am - so I need some experienced help with a decision. I've got 90% of the frame on reconstruction done and now I am looking to upgrade the front suspension I am looking at two akternatives from Vette brakes and products. The first is a light weight alluminum upper control arm and then replacing the coil cprings and shocks with their alternatives. the second option is going a little deeper with their transverse composite monospring system which (according to their ad) puts 2000 handling on a C-3 this alternative eliminates the coil springs. I see this later option advertised alot and I am wondering if anyone has added it - how difficult it was to install and how noticable the improvement was, Any suggestions appreciated - Ken

I'm new to the list and have the same exact question. We have just started a rebuild of a '69 coupe. I have read and heard a lot about the composite monospring being used in the rear, but I have yet to find someone who has used this set-up in the front...

I hear a lot of good things about the front composite spring set-up, but I haven't actually ridden in one...yet.
Don't know about the 2000 handling part, tho. That might be a bit of a stretch!
There's gotta be a C3VR member that has one of these set-ups...

Hey guys,
I just starting an install on a VB&P Grand Touring Plus Kit as well as some other mods. I considered the Performance Plus kit with the composite front spring, etc. But decided it was a little more kit than I needed. I've heard it's a great kit and the ride is very close to a C5 if you have modern rubber. My understanding is the kit is really about racing because of the adjustabilty it gives you. While I might take an occasional trip down the 1/4 mile track or a lap or 2 on the road course I'm hardly a racer but I do drive farily hard on the road so I'm hoping at $1200 less the Grand Touring Plus Kit will be what I'm looking for.... which is good handling when I want to go fast and a comfortable ride when I want to cruise. Oh, by the way, I'm also doing a Tremec TKO 500 5-speed conversion from a TH400, steeriods and new wheels and tires 17x 8 torq thrust II' s and though I haven't ordered the tires yet, I think I've decided on Sumitono HTR Z's in 245/45 17 front and 255/45 17 rear. I already have a ZZ4 crate enginge in the car too.

I went with the monospring in my 81. That and the rack and pinion makes it a new car in terms of handling. Installation was a snap. You also loose some weight up front when you take out the coil springs etc. I don't know about C5's but my C3 compares quite favorably compared to my brother's '92

Excellent imput guys. That gives a guy something to think about. It takes alot of info to prioritize when there is only so much money to work with in a life.

Ken,
I replaced both springs, Front and Rear, with the composite transverse mono spring.The front one is easy to replace. The car handles much better,is more stiff but is a good improvement. My Vette is a 1970 B/B.
The only disadvantage I noticed is driving on country roads where the pavement is not very smooth the car is a little jumpy.
Good luck
