3000m wide arches
Discussion
Hi Stu
I run Bmw E39 hubs with 5x120, so I can use std bmw spacers.
If you want to just space your 4x108 you can use something like this

If you want to alter from 4x108 to eg 4x100 this type can be used
http://www.ebay.co.uk/itm/hubcentric-spacers-4x108...
and you can even find them in 4 to 5 stud conversions

Although the Taimar is 4x114.3, so those Ford ones won't fit.
Should be able to find some 114.3 spacers though as a lot of the Japanese stuff uses the same PCD.
You may be better off having a machinist cut some for you. Wost wheels are hub-centric, and the TR6 hub centers don't project very far. By the time you add a 7-8mm spacer . . . Should be able to find some 114.3 spacers though as a lot of the Japanese stuff uses the same PCD.
Best,

Most spacers above 15mm are hubcentric
Like this set on ebay

But remember to measuer the center diameter and verify they match.
Nissan seems to run 66.1 mm center bore

That being my point. madsvlund said:

That model (S13 or S14) was the hub donor, for my car. I think the center diameter is different. http://www.ebay.co.uk/itm/Hubcentric-Bolt-On-Wheel...

Is it just me but i would feel uncomfortable about fitting spacers of any size a few mm yes but that size i am unsure noidea why
Can any of the experts fill us in here as to how they effect a cars ride etc

Few quick thoughts based on what I've read/seen people talking about on mini spacers and other stuff.Can any of the experts fill us in here as to how they effect a cars ride etc
Andrew
Pushing the wheel out, possibly moving the contact patch on the tyre towards the inside of the tyre.
I know on the mini it can cause the wheel bearing to wear quicker, especially on the big 13" wheels, but that might just be because the mini hub/bearings etc are at there limit already. Whereas the stuff on the TVR was originally on a heavier car, so may have better longevity anyway.
I believe it can also make tramlining worse. Maybe bump steer, but I'm not sure on that, can't visualise how it would effect it as the rack and TREs etc are still in the same place.
Bit of reading would suggest a wider front track can help turn-in, due to weight transfer stuff, but I doubt you'd notice on a road car.
Obviously the bigger you go, the more pronounced the effects will become.

A few geometric points on reducing ET (adding spacers or using rim's with a lower ET number.)
In general chamber and caster wont be affected, load on bushings will increase and the added flex will chance chamber, but in a negligable level. So don't worry on contact path, tyre load etc.
Bearing load will increase slightly on the outher bearing and rediuce slightly on the inner bearing, but don't worry, bearings are dramatically over designed in terms of load caracteristics, dynamic load range is around 3,5 ton per bearing where we are running around 150-200 kg per bearing. Wear will ofcause be sligthly affected, but again dont worry.
Major drawback is scrub radius on the front wheels. The triumph trunninon design do run with a scrub radius of 2" (distance from center of tyre to the revolving axis of the steering line's point on the ground) by offsetting the wheels will the scrub radius increase, and there by will the negative effect allso increase. The major problem is the tendency of unequal load on the front tyres will "pull the steering" , a little is ok in terms of informing the driver of skid'ing front wheels, lost traction etc, but too mutch will make the car dificult to control. A positive camber setting can have the same effect, just driving in the "truck tracks" on the highway can be a pain.
Modern cars run with very little and even negative scrub radius, mainly for safety reasons. But on out old cars, keep the front track as low as possible, and use as much negative chamber as possible (not more than -2 to -3 deg).
Bump steer is not affected by wider track, but the effect of increased scrub and the effect of too much bump steer feel quite similar from the drivers point of view.
On the rear will the busing flex and load increase, and thus give more flex in terms off toe,in under acceleration, but the TVR rear end is quite well designed so I don't thing it reaaly get's to a problem. My car is perfect on the rear (even the driver have problems controlling 250+ horses, short wheel base, LSD and wide tyres on a cold foggy morning. But it for sure wakes him up :-)
