Morning all,

So I finally got around to taking bluey out for a quick "up the drive and back" spin just to check things and also free the brakes up. Everything seemed ok except the front wheels seemed to be rubbing rather a lot, and not just on full lock. On the drivers side near there is a little nut which the tyre seems to rub on constantly.

I can only assume that the car is either too low or there is something else amiss. A couple of photos here to show the rubbing and one of the drivers side suspension arm (I know it's a tad sorry looking):








Any help or pointers would be much appreciated!
Kev

A pic on its wheels would be useful to assertain base ride height
What size tyre's are they.

That top wishbone looks rotton and could well flex under load. it's doing it on both sides?

Are your shocks compressing or have the wrong length springs which will have the effect of dropping ride height to far but it still shouldn't bottom or rub.

What sort of gap do you have with wheel on from tip of tyre to wheel arch should be a good 10-25 mm depending on ride height. The rear should show slightly more than the fronts, car should have a forward and slightly downward rake.

In the last pic, that's the n/s ?
If so is it just the pic or does that diagonal outrigger tube look bent? or is it my eyes!??!

Cheers for the reply!

I went round tonight on the way home to take a couple more piccies. The last picture above is of the passenger side (sorry, not sure which side is O/S or N/S!)

Drivers side:






Bolt that the tyre is fouling:



Passenger side






Both tyres are Avon ZV3 - 205/60R15


Thanks again,
Kev

I don't think I have nuts like yours......I will pop outside and check. Your tyres are standard size

I think they hold the fuse box in place, that's all I can think of off the top of my head.
That's a big old tyre you have there.
Your outside dia is about 627 mm
On a 205/55/15 it would be 606 mm

I run 215/45/17 which off the top of my head is 625 mm but I have no problems with rubbing.
That tyre is to big in my humble opinion but it still shouldn't be rubbing. I'd start to look carefully at those wishbones and ball joints for movement when under load.

The wheel position looks ok. Hmm!

205/60/15 is the standard size they came out of the factory with is it not? People only fit 205/55/15 now because the 60 profile is near on impossible to get now.

Thanks chaps.

Looks like I need to jack it up and take a look further! Any pointers on what I need to be looking for?

A knackered damper or spring wouldn't help, but I don't think that is your issue.

Afternoon all,

I'm going to pop over to have a quick look at this today to see if there is anything obvious that could be causing this fouling. Failing the obvious (and bear in mind I'm amateur at best!) is there anything I should be looking for?

I'd love to take it to an expert but it has no MOT or tax so can't drive it anywhere. Plus I'm trying to do this on a tight budget!

Thanks
Kev

Well I've had another look and from my basic understanding everything looks ok, albeit slightly worse for wear.

Could there be a possibility that the tyres are just too big? The fronts are both 205/60/r15 and 225/50/r16 at the tears.

Thanks
Kev

Firstly, 205/60/15 was the standard front size for cars upto approx 95-96. The rear size you have is for the later cars (225/50/16). Original fitment if your car was an early car is 225/55/16. So what age is the car?

If it's an early car I would expect the car is running too low, ( check the floor to outrigger corner dimensions both front and back, front should be 135-145mm min, and rears 10mm more.

Likely cause is sagging springs, shocks, as they all look rather tired. As mentioned those wishbones look tired aswell, are they twisting under load?

Are you seeing the tyres catch whilst it's on the ground or whilst racked up? Also can you. Onfirm there are no spacers between the wheels and hubs?

Cheers for the reply!

The car is M reg so 94. I took a few more photos today which may help but it all looks rather tired.

When the car is down it doesn't appear to be rubbing but when I took it out for a quick spin was when the rubbing occurred. I can only assume then it is when it is under load.

Probably shocks springs and maybe even worn ball joints.

So it basically sounds like the whole front suspension is knackered!

I'm guessing there must be some flexing going on as the tyre doesn't foul that bolt when just turning on the spot. I guess then the next question is how easy is it to replace the whole lot?

Kev, before embarking on a lot of expense, it is worth taking the car to someone who knows TVRs and will give you an honest opinion of what is wrong without generating himself a shed load of work.

Two guys I would recommend for this are:
Mat Smith in Downham Market, Norfolk (01366 386004). He is the best in my opinion, but is 105 miles from you. He specialises in the mechanical side.
Jools (Kits and Classics) in Chesterfield (07521 288875) - straight up the A38/A61 from you, a mere 40 miles. he is best known for his rolling road and mapping work, but is a competent TVR mechanic.

There is nothing wrong with any of the main players in the TVR market place that may be nearer to you, but from my personal experience I can guarantee a totally genuine opinion from either of the above, with your best interests foremost.

Mat has solved my wheel-rubbing issues in the past on my car with 5 minutes on the ramp and application of spanners in the right places.

Also, it is worth saying that a proper safety inspection by one of these experts is worthwhile, given the amount of corrosion evident in your photos, as some areas are a serious safety concern.

Sound advice there, the only problem is the car has no tax or MOT so I would have to put it on the back of a trailer.

Do you know of hand how much they would charge to take a look?

I have added phone numbers above - give them a call, mention my name and ask them. It won't be expensive and may save you a lot of expense and heartache. If you have a suitable tow car, a trailer costs about £60 per day to hire
