Hello,
May someone advice me on shocks please ?
What should be the spring rate and shocks for a gr4 race car ?
Does anybody sell them ?
kind regards
Philippe

hallo Philippe,
mine are from www.intrax.nl
sure not the "cheapest" but high quality and they can advise you on spring rates etc.
Are custom designd and build from their "standard" parts as it would be for a race Porsche GT3 as a example ...

Hi Philippe,
I was waiting for SOMEONE to answer your question but so far no one is stepping up...
As far as I know, there are no differences in shocks between a standard body Pantera and a GR4 Pantera. Please,if I am incorrect, someone help answer Philippe's question.
The real question here, as I see it is, what is the corrected setup for a Pantera Race Car? There are so many variables to consider that I do not believe there is going to be a single best setup for all cars.
If it is not a street car, IE: only on track, then the answer is going to be different than a car that sees both street and track use. The cars weight in each corner is important and how much droop is required will be important.
Philippe, if you could give us a bit more on the cars use and how much it weights, etc... then maybe someone with more Pantera Race Car experience can chime in here and help with your question...
Take care, Scott

Hi Scott,
the car will be a track car only, it'll weight aprox. like a stock car ...

Hi Philippe,
do you want your car to comply with the FIA regulations (group 3 or group 4)or are you just looking to build a fast racecar ?
If you want to build a racecar, Intrax is a very option as Barry suggested.

Hi Philippe,
If your Pantera is a stock weight I can set you up with a variety of high quality shocks that you will be very happy with. The Ridetech shocks we sell are actually built by the widely known shock builder, Fox Shocks. They have been favorably compared to Penske racing shocks but for a lot less money.
I could make recommendations for spring rates however this topic is very controversial. People use very soft to very hard springs on their cars for a variably of different reasons.
Most of the recent street setups we have sold use 250 in the front and 400 in the back. This combination has had very good feedback from all that have used it. It is, in fact, what I use on my car.
We also have a shock sale right know of 100.00 rebate per pair of coil-overs sold, when the old pair of coil-overs are returned. So that would be a $200.00 rebate for 4 shocks. This wouldn't make allot of sense unless you could get your old shocks to the US for a good shipping price since we do not cover the shipping of the returned shocks.
Even without the rebate, our shocks are top notch and a bargain.
Take care, Scott

Same here > i.e, using Intrax

Yes the car has to be FIA gr4 legal.

Scott,
Thanks for your help, the spring rates should be higher than 250/400 in my opinion, I sent you a PM ...

Yes, I agree... the 250/400 setup is for a street car. I can get away with it on my car because I have the electronically controlled shocks, and with a push of a button, I can instantly firm up the valving...
Take care, Scott
Does anyone have spring rate suggestions for Philippe?
Lots of garage door advise but no technical support for an actual Pantera!!!

Only one running a race Pantera with a similar weight and weight distribution, similar ride height, running on 15" wheels (how wide?), and race tyres (what brand?), could possibly answer this question, or of course, any suspension specialist...

Your right Kid, I never claimed to be a suspension specialist. Just a Vendor with honest prices and access to top quality parts. That is why I was asking for someone to help Philippe with his questions. Springs Rates however, is not rocket science.
Let's go a step further :
wheels will be 15x10 and 15x13
tyres will be Avon race tyres (probably)
weight distribution will probably be like 40/60%
ride height : don't know (but low)
I was told something like 450 and 500 and up ...

Springs, I would start at 450 front and 550 rear and see how it rides. The shocks though, puzzle me.
Hello guys
I'm going to make my decision soon
It seems that 450 /650 is a good option for a track car ...
Any late advice please
kind regards

Why not, after all, the springs themselves are not that expensive, and not that hard to change - the rest of the shocks though, can get expensive...
I run 400/500 on my widebody GT5 for street, I'd say start at your suggested 450/650 and go from there. It's going to be trial and error and even specific track dependent, but as Kid said shock springs are relatively cheap.
My only other suggestion is get a hold of Patrick Hals, he owns and races Candy & Andy Group 4 cars. His website with e-mail address is here http://www.detomasogr4.com/cars.html
Or call Dennis Quella at Pantera Performance Center and ask what he runs on his race Pantera (that is a tube frame car so a bit lighter).

There is a 1974 Pantera GTS (like a Grp3 car) racing in Australia and it is fitted with 450 Front and 750 rear springs. It has 15x8 and 15x10 wheels with Goodyear Bluestreak tires.
I'm afraid you're going to have to guess and try. Ultimately, it depends on how rough the tracks are in your area, how heavy your complete front suspension assembly is, how high the chassis is set and a few other factors. If you're serious about this, you'll wind up with a boxful of springs because each track will need slightly different ones. Ideally you want the car to not quite touch down the front airdam or any other part under max braking or traversing an 'average' bump. Too soft and aero loads at high speed will push the chassis down further than you'd think possible while too stiff will cause the car to hop high over bumps- 'there's little traction with the tires in the air' (Carrol Smith- 1980).
The rear is less important but should stay balanced to the front. As an example, our lowered street Pantera has been severely lightened so I can run 250 lb front springs & 275 lb rears (plus I get 45 lbs more per corner from using Koni gas shocks who's high gas pressures add to the spring pressures), and not have our Revson front spoiler touch down on track or bumpy public roads. So it's a highly individual thing depending on the car involved.
AVCO non-plated springs from Speedway Motors for my Koni gas shocks are less than $50 each & install in 30 minutes. Street Panteras are typically sprung way too stiffly IMHO, and track-only Panteras need better damping than most street shocks provide, apart from the spring strength used. Good track shocks may have remote fluid chambers, will be priced around $1000/corner and have adjustable-everything. You'll need it, too. A set-up notebook will help keep you from getting lost in the adjustments.

So what some are suggesting is a set of springs for the track, specific springs for specific tracks and separate springs for the street.
What is a good spring rate to start with for the street?

300/450 to 350/500 is a good starting point for a stock Pantera. Nobody really needs multiple setups for a street Pantera that does occasional track days.
A dedicated race car is a different story...
I use 250/400 and am VERY happy with the performance on and off the track. I do have electronic shocks to stiffen them up for the track.
