Wheel arch clearance

[scruggs]

Now call me old fashioned but I always thought the gap between the tyre and the wheel arch should be the same on both sides of the car.

Recently got my mk1 Tuscan back from a service that included all 4 shocks replaced, rear wishbone bushes and front track rod ends.

Looking at it this evening parked on the drive the offside rear gap between tyre and wheel arch is approx 1 cm more than the nearside (roughly one fingers width for the average adult human, three fingers one side, two fingers the other). Actually quite a noticeable difference when looking at it.

Is this normal??

I'd imagine they are supposed to be the same.

Assuming you're parked on the level and the car hasn't been jacked, lowered and not moved.

It has covered about 100 miles in the last week. Handles far better than pre-service, less tramlining. Parked on a reasonably level driveway but slightly rear end low.

Doesn't sound normal to me.

Just checked mine and the gap is equal both sides.

I'd be popping back to whoever did the work personally to get them to check it.

TVR bodies can never be considered symmetrical in any plane.

Hence, all ride height measurements are always floor to chassis , not body.




Martin, how's the Tuscan?

Matt (sorry)

Fantastic thanks Ant, feels a lot smoother and less lumpy if that makes sense.

Just chuffed I'm lucky enough to have you guys on my doorstep.

Back in for that little bit of chassis work when you can fit me in.

Trust the Tam is well

Tam is fine Matt , lol.

We had 3 tuscans in that week. A Martins, a Marks and yours........

My car was corner weighted and it did not sit level because the ride height on the drivers side allowed for the presence of the driver

I'd suggest you measure the distance between a fixed point such as the rear corner of the 'C' pillar to the top of the wheel arch on both sides of the car. You may find that the measurements differ as many TVRs are not symmetrical as mentioned by Ant above.

Thanks for the feedback everyone. Seems like the advice is 'Don't Panic' it may be normal. It still drives ok!!

It's just TVR bodywork... All Cerberas were the same also, a full finger's difference with one's hand between the wheel arch and tyre.

Mine is the same, measurement from outrigger to the ground is the same, but about a fingers difference between wheel and body.

on my car it is 40mm approx on the front 2, beatween the tyre and the arch, and on the back 2, is 60mm approx beatween the tyre and the arch. i know it is built a shed as they say, but it can't be that bad of a built quality. i would check it out from a reputable tvr company if i were you.

The difference in measurements on the fibreglass isn't down to poor workmanship but the fact that the cars were mostly designed by eye which in some cases has resulted in asymmetric bodies with different clearances from one side to another. Also it does depend on how accurately the body was mounted on the chassis in some case with regards to clearances.

As mentioned earlier the only accurate way to measure the distance from the ground to your chassis and from the chassis to your suspension components.
