What I've learnt today

[Urban67]

That inch wheels definately do not fit on my 350i
which is a pain in the backside as I've already bought them
they do fit on but if I want to go round corners I may have a problem

nice wheels though


looks like I'll be sticking with the originals and putting these on ebay

...Sorry for laughing but they look like 10" wheels..What's wrong with your current ones?..Oz split rims are a good looking alternative...Someone on here may have a set or something similar...Ziga

That really does look weird, did you take any pics a little further way, so we can see the overall effect. What size wheels were they?

[Mr Tank]

Looking at the tyres more like racing slicks!

Are you certin there normal rims look more like fancy space savers!

Ha ha, you are quite right the photo does look a bit odd, that's because the car is jacked up.

I'll post a couple of photos tomorrow without the jack
The wheels fit but foul on the front of the sill when going to full lock
Nothing wrong with my old wheels at all, just fancied something different.



This photo is a little better but still jacked up

Probably a lot of fun in the wet!

It's a shame they don't fit properly on your car, as they're nice and contemporary.

When I picked mine up it had 225/45/17's on it.



They didn't look too bad, but the car handled like a bag of shite, tramlined down the road and corners could only be taken extremely slowly and very very widely!

Thank God I was able to change them

They dont look too bad actually...When you say failing on the front sill do you mean the front inner of the wheel arch?..Does it happen to both wheels...For some reason..Probably a wonky bodyshell my N/S wheel used to do it with the original wheels and tyre size...I had to have the caster changed slightly to avoid the burning rubber smell whenever i was turning, Especially on motorways at the legal speed limit ..The only draw back is a slight wander to the left if i let go of the steering wheel..Which is something you dont do that often anyway...I suppose they have a low profile tyre anyway but could they possibly be lower?...cheers..Ziga

The back of the wheel catches on the wheel arch where the front of the sill is as the sill does sit slightly proud into the wheel arch.
Hope that makes sense.

I am beginning to think that the ride and handling will be compromised, there is a lot to be said for 14/15 inch wheels and fat tyres.

Chris,

Were they off the shelf or custom offset which Team Dynamics are able to offer?

I had them produce custom offsets in 9 x 18Fr & 10 x 19 R and have not problems lock to lock with 255/30/18 Fr and wider rears but did modify inner wheelwell.

My SEAC must have a little more room?

Have you tested them with the car on the floor?

While it's nice to have a change of wheels, there is plenty to be cocked up if you consider departing from the original wheel and tyre sizes that your TVR was born with - such as Ackermann Angle, caster, camber, slip angle, offset, oversteer, under steer, etc, etc. The dark art of chassis design is ingrained into vehicle manufacturers and the lads and lasses up in Blackpool were particularly good at it. You can really mess things up and induce dangerous handling characteristics to your pride and joy by using wheel spacers, tyres with different rolling circumferences, tyres with different aspect ratios, sidewall stifness, and even tyre pressures, if the original factory geometry settings are not maintained. They may not manifest themselves until you push towards the edge of the envelope, or find yourself reacting to an emergency situation caused by some other numpty, but the results could be disasterous.
I'm not suggesting that different size wheels, plus spacers can't be used. I'm sure there are many professional suppliers who know what they are doing, it's the age old "Caveat Emptor" thing (that's Buyer Beware, to those who never did Latin at Grammar School, like what I done).

Wyn,

Yes,

Andy,

I hear what you say but have faith in my guys.

They have a wealth of experience and have incorporated chassis improvements into my chassis.

Blackpool may of had good chassis design experience but I feel they let themselves down in the flex department which possibly effects all those parameters you mentioned?






Mine is the slowest restoration ever.

While it's all beautiful, I really like the cast iron rotors

Seriously, that's new to me. Will you have to strip them or will the paint burn off quickly? Grady

[Transmitter Man]

Hi Grady,




I went for black zinc;


I'm hoping that only the pad contact area will wear over time and that the zinc will help reduce the onset of corrosion while still looking good.

We'll see.

Hi Phil

I bought them from a chap who races TVR's on the spur of the moment. I was buying some other stuff off him at the time.
Have you made modifications to your chassis to improve handling?

Interesting to see the old style diff carrier.

[Transmitter Man]

Chris,

I think the biggest improvement will come from stiffening up the chassis.

You cannot believe what it was like even after we had replaced the seamed tubes with seamless and corroded steel with new tubing.

Hi Phil

I'm doing my restoration in a slightly different way as I've bought a chassis that has been repaired and powder coated with a load of either new or re-furbed running gear. So I will be building that up when I'm ready move the engine and gearbox and the body accross. My current chassis is pretty bad and I was offered the new one.
So are there any mods you would recommend to my new chassis before I start the re-build, now would obviously be the perfect time to get it right.

love your brake discs BTW, where did you get them from?

cheers

Chris
