T350 suspension geometry settings
Discussion
Does anyone have any geometry settings they have used on their car whivh they believe has improved the handling.
The car had a full wheel allignment done before i purchased it but it feels very nervous and doesnt fill me with any confidence.
It is on Nitron shocks with standard size tyres set to 26PSI.
Thank you in advance.

I can't help with geo - Matt Smith set mine up (perfectly).
However, I would suggest 26PSI is too hard.
The type of tyre; the side wall rating and the pressures make a huge difference to how the car feels.
I run 24PSI all round on Goodyear Asymmetric's (I know some people run even lower pressures). The steering is very direct but no 'nervousness'

The standard factory Geo settings are listed in a PDF in the files section of the TVR T350 Owners group on FB.
They are very conservative and probably aimed at straight line stability , understeer (if possible in a T-Car) on turn in.
These are minimal camber front -0.5 rear -1.25 and relatively high rear toe in -3.0mm and safe toe-in on the front -1.5mm.
Ride height is stated as spring length at ride height which is for the factory springs/bilsteins so N/A to the Nitrons, though running a low ride height may make the car more nervous especially over roads that has it engaging the bumpstops . The Nitron spring rates may also affect how the car feels on bumpy roads as they are (usually) significantly stiffer than the springs the factory fitted to the T350. See the Harry Metcalf recent video on the Cerb he tested , a lot of his comments will apply to a T350 on Nitrons regarding the ride etc. I run Bilstiens on my T350C formaly the Tuscan S retro fit option and now Sagaris spec ones, my spring rates are stiffer than Tuscan S rates but a bit lower than Sagaris rates, the latter are very close to what Nitron usually (used to?) fit to thier shocks (Subject to what is specced at purchase time) & I feel that they, Sagaris spring rates, are a little too stiff for bumpy northern moorland roads , but thats a personal view YMMV.

See here https://www.pistonheads.com/gassing/topic.asp?h=0&... which covers the T350 as well.
I drive 1,5 (21,7 psi) bar at front and 1,7 bar a ( 24,6 psi) the rear.
It makes a big difference driving a later steering box with longers arms.

if you're not happy, get it to someone who knows how to set them up, topcats, centre gravity, str8six, (other recommendations too but i've used these myself) someone who can corner weight it, also front tyres can be a 40 profile with softer sidewalls as the 35 are difficult to find. i've got sp12 wheels that have helped.
