Wheels rubbing
Discussion
Spiders on the rear. One rubs on the outer part of the wheelarch when on country lanes. I'll get the suspension levels checked first - it might be that a little more height stops this - but in case that doesn't work, does anyone know what distance exists between the inner wheelarch and the wheel/tyre? I'm considering having the inside of the wheel machined slightly to move the wheel inwards (I'd do both sides of course). It would only need an eighth of an inch I expect.
I'm not keen in changing the ride height much more than a gnat's tadger. The car doesn't bottom out and apart from the rubbing, rides and handles very well.
What are the sizes of the Spiders relative to the SP wheels? Aren't the SP rears wider? If so, how do they get around the wheelarch rub problem? Do they sit more inward?

Just the driver's side. There's rubber on the inside edge of the arch and a noticeable stripe on the tyre (noticeable but not signifiantly worn).
Admittedly I'm a fat bastard, so that might be the cause of whay it's on one side only, and if that's all it is, it's easy to adjust with ride height adjustment, however if there's enough room to move the wheels inward slightly, I'd rather do that. Having the capability for full wheel/suspension articulation is better. The car doesn't need stiffening up at all. In fact it rides so well, it'd be a shame to do so.

There is a noticeable mark all the way around the outer edge of the rear tyre, this is where Joolz and I didn't strap it down tight enough on the rollers. This may be what you are thinking is being caused by the tyre catching the arch, is there any evidence on the arch. The rear set up of the car is soft as opposed to the front that is set firm, for me this is the way I like the set-up of the car and you seem to be enjoying it that way too.

It's definitely rubbing. The mark on the tyre is fresh, and was hot when I got home. The rest of the tyre was grey on colour whereas this was black and fresh.
You can feel hot rubber on the wheelarch too. It's really only the smallest amount - not enough to groove the tyre - but noticeable.

Mine did the same all the time when I got it.
I changed the springs and stiffened up the shocks and it solved the problem on all but the very worst roads (and then I have to be thrashing it to get it to rub).
The passenger side on mine never rubs.
I've got 16" Spiders, if that makes any difference to anyone trying to solve this one.

My previous 4.2 cerb (fitted with 18" spiders) did that at speed and with a full boot of luggage on compression dips. Drivers side it used to ridge the shoulder of the tyre and if you rub the wheelarch with your finger there will be an associated film of rubber on the inside edge of the arch.
If you check the car side to side you will notice that the cerb body is slightly offset to the passenger side.
I cant recall how it was finally solved on my car, it was either that the shocks have adjustable collars and just needed to be wound up a touch or you could change the tyres to a less square shouldered type or a width size down i.e. 245 to 235 or 235 to 225

No, i was worried at the time but check another and you see a large number that are slightly like it.
This came up a few years back and I cannot recall if every cerb is like it or every cerb that came out of X mould is like it.
Any with the issue would I suspect rub their drivers side wheel arch if fitted with spiders, filled with petrol and luggage and driven over a yump.

I Have the SP wheels, after spiders.
When I picked the car up from Mat and the chaps at Silverstone Performance it felt a bit weird at first. I was used to the fairly heavy front end feel of the spider clad Cerb. Initially the steering wheel felt lighter in my hands.
Maybe I had become accustomed to the chunky freeelandeer wheel of my daily driver.
Due to the initial lightness a period of aclimatation(sp) was required, so a few days later I was out there attacking the roads in the way only a way a Cerb can.
Much better turn in more direct, you can see (in your mind’s eye) the tyre edge and the curbs more accurately. The lightness is transmitted through the whole car, now as we all know you have to push fairly hard to unstick a Cerb , less the stamp on it brigade.
The drive is transmitted straight to your hands. Yeah you can spin it up driving out of a nice undulating roundabout on opposite lock, but you know what’s going on it’s in your hands. And that is control...
You have to stay committed, to get the best out of it, but I guess that’s the same all round...
That’s the difference between q set of heaaaaaavy spiders and the lightweight SP wheels.
I would like all to note, I am not on the payroll, just a very satisfied customer.
I didn’t mention the finish, oh god. You go to see it. One of my wheels had a blister in the paint, Mat in conjunction with Greg at Newlyn designs, resprayed all the wheels to be sure of a color match. Let me tell you about the finished result. Spectacular is the only way o describe them. Believe me I am a fu09er for detail but these are the nuts.
This gave me a chance to change back to the spiders, seriously, it was as if some one had attached a bag of spuds to each wheel, it was massive.
Anyhow, your question. No I don’t think they will foul the arches, but as we all know, no two Crrb’s are the same.
I would have thought Mat at SP would let you have a go with the wheels before committing.
Give them a bell.

None of the characteristics described are anything to do with the replacement of wheels.
Grip, handling progressiveness and steering feel as described are tyre qualities, which were presumably changed at the same time?
