Is there a better suspension geo set up than TVR's settings.

[Jim Green]

Recently had a full geometry set up to TVR's settings, and didn't really notice any difference.

Is there a better set up to use, as regards to camber, toe in, toe out ?????

What shocks do you have? What year is the car?

My car was set up specifically for my car by Derek the Absolutely Shocks man. He knows what he's doing so will set a car based on the settings that feel good for that car. I have Gaz Golds and made a big difference to my car.

I also made a lot of other changes like tyre pressures, matched the tyres on the front axel and they also match the backs, changed the brake discs (warpped) and had new brake pads.

Car is December 2002, Toyo R1's all round (Brand New), and standard Suspension.

Just about to fit Gaz Golds (Just about decided......Finally), and then i'll have the the geometry done. Don't want to pay out for a full geometry set up using standard TVR settings, if there's better settings out there.

Not trying to steal anyones secrets, but if I knew what to set it too, then I can have it done locally. Really can't afford to drive around the country to get to one of the TVR Suspension Guru's, when I have good companies in my own area, who are willing to set it up to whatever I ask for. Problem is that they're not TVR Specialist and don't have any other figures to go bye expect TVR's own settings).

Want it set up for fast road (Not Track). Standard setting appear to be very track day oriented, and I'm looking for a more everyday road friendly set up. Softer (Hence Shocks and Spring Change), and a little less darting around on "A Roads" than it has as standard.

Had a long conversation with Derek today about just such matters. After a great deal of testing he has come up with the following settings which give the best ride & handling characteristics for fast road use and occasional track days. Should work well with Gaz Golds, since that's what he uses.

Front is slightly different from TVR settings, to give a very slight understeer (easier to control & less tail happy) on hard cornering.

Front:
1mm Toe in (0.5mm per side)
0.5 - 0.75 degrees negative camber

Rear:
3mm toe in
1.4 degrees negative camber

Recommended spring rates are 375 lb front, 300 lb rear (slightly softer than a Tuscan 'S', but dampers can be firmed up slightly).


Just need Jamie Oliver to mix those ingredients with some magic spanners and you have the recipe for a perfectly planted Tuscan with confidence inspiring handling !

You will find many variants on this theme Jim and I have tried most of them.
The revised factory settings of March 2005 were as follows.

Front
0.5 to 0.75 Neg camber
1.5mm (12minutes) toe in overall, divide by two for wheel toe

Rear
1.4 degrees neg camber
3.0mm (24minutes) toe in overall

I found the following small changes to be slightly better on standard road use

Front
0.75 to 1.0 degrees neg camber
1.0mm (8minutes) toe in overall

Rear
As factory recomendations above

For the trackday heroes I would run more front camber and work back to parallel by the time I hit 2.0 neg camber, you can run a bit of toe out on wet days.

Derek & Alan : Many Thanks for that info, Really Appreciated.

Derek : Assume those spring rates that Alan mentioned would be right for my requirements too ????? (Fast Road, No loose fillings after going over a manhole cover). Order will be with you very shortly.


Many Thanks

Jim

"Recommended spring rates are 375 lb front, 300 lb rear "

How can i check if correct springs are mounted?

My problem(Tuscan Mk1, 2000 built)
If i adjust damping a bit softer and going fast on bumpy roads
it feels like a trampolin on the rear.
If i adjust damping harder it feels to hard for normal roads
and highways(uncomfortable), but the rear is under control

Hope for help

Not sure how you can check (depends on type fitted) but sounds like the springs are too strong. Shocks can't control them on soft settings, and way too hard when turned up.
