Specing up coilovers
Discussion
I think I have finaly saved enough to buy a set of coilovers for the 2500M. (the old ones gave up on the way back from chatsworth and dumped all of the damping oil all over the road!)
I am quite tempted by some of the 400 series Protech dampers.. But wonder what other people have used?
To those that have replaced coilovers; what is the "prefered" open and closed length for front and rear, and the prefered spring rate for a slightly lowered and stiffer ride?
I estimate the correct springs to be 300lbs front and 225lbs rear, but would rather get it rght first time than work on trial and error!
So any thoughts on the "ideal" setup for fast road use would be appreciated.

There's this: http://www.pistonheads.com/gassing/topic.asp?h=0&a...
and this: http://www.tvrna.com/tech-m02.html to look at. As this type of stuff is always about compromise, it is important to know how little you care about your backside and your kidneys.

Hi Bernard.
Yes, I had read that thread, its very useful and I could figure out a "compromise" from that information. I was curious though what other people had chosen and what they thought might work...
To be fair, the rear dampers are so bad (IE they no longer provide any damping) that the car handles like a trampolene..... it would be fantastic if it was nice and stiff!

We have Leda supsension on our 3000S turbo. Very good with good setting easy to find and ride height adjustment. Its not to stiff on spring rates.
Race car has Nitron adjustable supension with adjustment for ride height, compression and rebound - the car is running very stiff springs (for now at least).
For road use, the Ledas are excellent and have a single knob to adjust compresion and rebound - they would be my recomendation if they are still available.

I had not come across Leda before... Just been reading a few websites with information on... they look interesting!
I dont supose you have any idea what open/closed lenghts you have and what spring rates you are using do you?
Open and closed lengths are "standard" - but I'm not sure what that is.I dont supose you have any idea what open/closed lenghts you have and what spring rates you are using do you?
Road car is 225 rear, 350 front.

John,
My thoughts are that Leda spec. front and rears of different lengths. Mine are and all the ones I've fitted in the past were.

I bow to your vastly superior knowledge. Mine were fitted when Simon had the car - I just had them rebuilt.
I do know they are shiney and they seem to work quite well..
Leda's were the best I had on my Taimar, mixture of road and track/sprint use. I also had Armstrong, Spax and Koni's on the car at various times and if purely a road car then I would vote for the Koni's as they gave the best ride. Spax are not my favourite, problems with the chrome plating on the piston ripped the seals apart (several times) and Spax on one occassion managed to send me two different shock absorbers for the front of the car in one box! Some tired Armstrongs were on the car when I bought it, hardly any damping at all!
But as usual, I would contact Adrian (or any other reputable TVR specialist), tell him what you want to use the car for, and ask him to supply a set of suitable shock absorbers and springs, his years of messing about with M series cars (expertise) mean that he has done all the hard work in the past for you.

All I can say John is that you can't be as portly as some of us other owners (who need stiffer springs). Eat more pies!!

Unfourtunately Dave I am also an instant lowering kit these days, but I've never liked the car too stiff. What I also run, is a thicker front ARB and a rear ARB.davidy
John
AS different as John and John...I agree with John, I like the reliability of the Leda's and personally go down the less spring poundage with ARB route, something that the cheaper shocks cannot live with. Racing drivers tend to like a stiffer set-up, but then most circuits have nice smooth surfaces.
