Alloys aftermarket or Something else?
Discussion
When you say sent away for a repair, is it a method whereby this is acceptable?fredd1e said:
If my memories are correct I think early Cerbs ,used a ET43 offset (for 18" Spiders ) front and rear , but later ones used the T-Car Spiders which are ET43 front and ET33 rear . All are 8.5" width. There are views that an ET40 offset works better for front steering feel/kickback? etc but an 8.5" rim width may put the tyre close to wheel arch (and other bits when turning) . Bola do (or did ) a range of wheels that offer custom offsets to fit, the downside (imo) is they use hub center rings (plastic) to take up clearance between hub diameter and wheel though most aftermarket alloy makers will do the same as few offer custom wheel hub bore measurements to fit CERB/T-car hubs (in Blighty) . Maybe the sportmotive/Motoclan wheels will be a direct hub fitment ? I have a set of Bola B11 (19" up) for my T350C in ET40 offsets front rear (9.5" rear 8.5" front) with 225x30 front and 255x30 rear tyres. These are lighter (with tyres) than the 18" spiders but I recently started to get rear axle vibes at national speed limit speeds so have just refitted my spiders (no more vibes) . Note the car drove fine with the 19"s upto the point the vibes started and I had decent wheel arch/tyre clearance but I also dont have it sitting on the bumpstops & have Sagaris dampers/springrates to counteract potential bottom out issues at the rear , which they seem prone to on undulating roads on stock factory spring rates. also the Sag bilstiens have a longer progressive bump rubber, unlike the oem or billy retrofit shocks for Cerbs/T350C etc so assist in bottom out as the car transitions to the solid state from the suspended spring rate unlike the originals which is a hard bump/bottom out.
Early Cerberas didn’t come with spiders. They were introduced in about 2000. The majority of the post 2000 Cerberas came with them and used ‘fronts’ all round. A few cars came with fronts and rears. The Nige said:
I picked up a nail but hadn’t realised how much of a problem it was going to be sourcing the rear tyre 245/45 16", no matching tyre in stock, the tyre was removed and sent away for repair. Had to use an old wheel and tyre I had at home.
About fifteen years ago I tried sourcing a pair of 245/45/16 while at a track day at Spa in my 928Even then it was virtually impossible, we spent ages driving around every tyrefitter in Liège, eventually finding a pair that had a ten year old date stamp
It seems there were only a handful of cars fitted with this size from the factory, including the S2000 and 944 Turbo, hardly surprising they're so difficult to find

There are! Blackcircles and others have Pirelli P Zeros. For classic car tyres, you should always look at Longstone Classic Tyres. They have the P Zeros plus Cintauratos and some Michelins.
The Longstone Classic site is fascinating, thanks for thatHowever, I could never justify the prices that period correct tyres command
You're welcome and I understand.
They have a clever niche in that if you want your concours classic to look period correct, then you will pay for the correct period looking tyres, and of course they will be getting them made in small batches and they will be slow sellers, so they have to factor that in to the price.
The point is though that you can get 245/45/16 Pirelli P Zeros, and from cheaper sources, still not cheap, but they are a far better tyre than the Chinese etc. alternatives.

That is an interesting statement, Gazz.May I ask what you base it on ?
The production figures I have are:-
| 1993 | 1996 | 1997 | 1998 | 1999 | 2000 | 2001 | 2002 | 2003 | 2004 | 2005 | 2006 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 1 | 195 | 441 | 372 | 271 | 168 | 102 | 72 | 87 | 61 | 4 | 1 |
Now I believe that Spiders were introduced with Series II, which I believe was September 2000 so if you split that ⅔ / ⅓ that would give approx 112 / 56 which would make the total of Series II+ Cerbs approx 380
and you're saying "Most of the Cerberas that came with spiders came with fronts all round".
It just makes me think why have both my sets got ET33s on the rear ?
