What springs did you fit in your vette ?
-
I used standard lowered HQ springs in my 77. Fulcrum measured my old ones and said they are the same.
I'd use them again.
:cheers:

Hi Dave
Here is the stock 71 small block spring next to a Pedders HD lowered HQ-HJ (non RTS) spring.

Exact same diameter etc.
In my 71 I used semi coil overs as I wanted to set height exactly and have more control.

So they'll fit, but what about ride and ride height ?
What else have you guys tried ?

Complete ride height control

The semi coilovers from Speed Direct let you choose from a number of coil stengths as well as the QA1 dampers having adjustable rebound and compression control.
Make it whatever height and as soft of hard as you like.

I'm trying to keep a stock appearance, but that's a real nice setup. :thumb:

So lads has anyone actually said what the ride height at the front should / is ?
I think we should have a benchmark
My front has sagged over the last 6 months (since refitted motor) and I'm thinking of getting a new set of front springs. the point being what is in it now and what standard ride height be against say Pedders HD lowered HQ-HJ (non RTS) spring. ?
-
To add to the confusion, Pedders list this as a spring for 63-82

Can't remember what brand. You can give Fulcrum a call - http://www.fulcrumsuspensions.com.au/ (http://www.fulcrumsuspensions.com.au/)
The wheel arch was same height as the tyre. They did make the front end pretty stiff!

Thanks for that
I picked up a used pair from Bfit (thanks again Bob) I'll clean them up and try them first.
I can always cut a little off if too high.
Cheers

I cut only 1/2 a coil off my 71 stock spring and they are too low! :tears:
Mind you.....you can't expect much from 40yr old springs.

:eek: I think we've all been there, if we're honest
This is a good article on how (and how much) to cut a coil spring

The measurement on my 80 corvette front and rear from centre of wheel to top of guard is 385mm.

Chris, Me Vette just looks and feels as though the front end has dropped bout 12 mm :banghead:

The 72 in my signature was a bone stock base 350, with less than 80k miles on it.
Your car looks pretty low compared to that.
-
Hey Jethro that tape reads 340, my 81 measures 365 its a bit low !!!
-
Now that's sounds bout what I was expecting :thumb: Might get me self a new set of front springs from VBP

:agree:
I think you'll find it's been lowered. That is the same height as the lowered HQ springs I had in my 77. Standard height, the guard is usually about 1 1/2 inches above the tyre.

I have the 550 lbs on the front of mine from VBP they have a final setting of 375mm to the top edge.
Motor front weight will make a difference as well as your tyre size.
Mine is a 350 with alloy heads no air, tyre size is a 255x60x15 IE 27 inch.
I think they are a little high going to take them down to 360, they have been in the car 12 months now and have settled with about a 1000 miles on them.
Hope this helps out.

Ross,
Same same buddy Alloy heads and such :thumb: The 550 lbs on the front of mine from VBP they have a final setting of 375mm to the top edge !
375 ?? is that from the centre of your wheel to tip of guard as I pitured bro ? As when I lok at the VBP site they say "Those Want even greater handling capacity? These springs will upgrade your Corvette to F-41 or Gymkhana specifications and lower the vehicle approximately 1".

Jethro
yep center of wheel to top lip just as you have shown in your photo. It originally had F41 on it but were sagged down so just went with the new set up, the original F41 springs are 430lb or very close to that, the 550 lb are big block springs they sit just about right but I would like them down a touch 1/4 to a 1/3 cut on the spring will do it nicely.
They are firm but I have balanced the suspension now and its really close to 50/50, just a tad over steer if you really get on it coming out of a corner but really good going in.
Bilsteins sports all round 7/8 front bar, 7 leaf rear and a 9/16 rear bar original bar not a after market bar..
Need to get the cross-member stiffeners as there is still some flex in the rear end.
Really stiff not pleasant on the way back from Megalong Valley last week down the Bell Line. But its meant to be got into and thats when its really fun.

Thanks Ross,
I fitted the Vbp 11/4 front bar, Front Spreader Bar Kit & Rear Smart Strut Poly ended Kit from and running a composite rear spring for Vansteel love the feel of me Vette on the road just not happy with where the front end has dropped to over the last 4 months or so, since I've refitted me engine (and it's lighter than before) front needs to come about an 1" so I'll bite the bullet and go 550lbs Vbp front springs

I don't think I'll be using the BB springs that Bob gave me, so your welcome to them, cleaned and painted.
Let me know
