Hada fantastic day out in the sun yesterday. Drove some nice twisties (picked the short route on Tom Tom then avoided all the bug roads) down to Seatown and back.

When we hit roads with bad surfaces, and some of these were quite fast roads, the Tamora was jumping all over the shop.

Question is, for all you other Tam and 350 owners, is this (a) a symptom of the factory fit shocks and means that I'm now at the point of needed to spend MORE money to upgrade? Or is it (b) just that I need to get the geometry checked? Iknow, I know, without you actually driving the car you can't say categorocally - but in your experiences is this something that can be fixed by (b)or is it £1200 time and option (a).

Cheers in advance....

possibly geo, but also as tyres get hotter there presure rises (found this out on the track) which then makes for some interesting handling....

Yeah; didn't check the pressure when I collected from the service. Usually run at 24. Mmmm. WIl do before and after checks today.

May be due to the shocks as well! I've been told that the car can be very jumpy on unsmooth roads, but it's apparently amazing the difference upgraded shocks can make!
Told Gaz Golds are excellent and not quite as harsh as nitrons etc., so i think this'll be the route i'll be going down at some point.
Of course, i'm sure they'd do the geometry during fitting of the shocks, so might be worth thinking about!

I was seriously considering Gaz Golds myself, for exactly the same reason - handling just didn't feel at all right on anything other than smooth roads (which are pretty rare in West Yorks!).

However, after a long chat with Ian at Torque RVT, I just had the geometry checked. It was way out on all four corners. Now it's been set up properly, it's like a different car. I guess upgraded shocks are even better, but for a very small outlay, I'm really pleased with the handling now.

I find the tyre pressures make a huge difference. I like mine on 24psi which makes it feel the same as the karts i race!

I had a full Geom check at Top Cat Racing and a set of Nitrons, a big difference. More control at high speed braking and keeps in a straight line on uneven surfaces. Recommend them.

It seems that there is a common thread, that changing the shocks does make a big improvement.

However, with a prospective BIG bill for engine rebuild coming up I'll go the easy and cheap route first.

Then, maybe, if the pockets are deep enough the upgrade might happen at the same time as the engine. In for a enny, in for pound sort of thing...

Changing the shocks does make a big difference but I had the pleasure of setting up the geo on the previous poster's Tammy and new shocks would not have made any difference to that car handling wise.

Shocks and springs do help on the banging and crashing but having all the wheels pointing in the right directions helps just as much.

I was told by the dealer at the 18k service that they didn't bother checking/setting the geometry because all the tyres were wearing evenly and it was OK when they road tested it.......

Can it go out noticably in 6k miles and not show in tyre wear? Actually, that's probably a daft question.

Yeah. Guess I should have mentioned the bumpy-road effect.

Geometry settings on a T350 are critical it seems !

Probably fair to say that geometry is critical on any powerful rear wheel drive car. Toe and camber settings are important on the rear for traction (as is rebound on the dampers) and turn in and grip on the front is variable, depending on settings.
