My Spiders are predictably getting bent by local potholes. Searched long and hard for replacements - very difficult in relation to staggered size and high offset for rears. Making the investment, they have to be good quality and have great aesthetics. Aware of Speed 12 wheels but not a fan of the 12 spokes - wouldn't rule them out altogether.
Have narrowed it down to TSW rotary forged Bathurst, dropping a size to 17 inches. Gunmetal would go well with Imperial Blue, I think.

Any advice in relation to fitment would be appreciated. Or anyone with relevant experience of fitting aftermarket wheels. I have been advised that I need to think of all the movements a wheel can make, not just the static clearances.

Current set-up:
Spiders front 8.5 x 18 et 42 with 225/35 tyres
Spiders rear 8.5 x 18 et ?33 with 255/35 tyres.

Proposed set-up:
TSW front 8 x 17 et40 with 235/40 tyres
TSW rear 9 x 17 et40 with 255/40 tyres

Not worried about matched set of tyres.
Rears - same distance from arch but inner edge of wheel is about 1.3 cm closeer to strut.

Cheers!

Bola have just started making a Spider rep.. Looks very similar to the original spider wheels but lighter, and I would hope stronger..

Yes Bola B7 looks v similar the Spider but widths are not ideal at 8.5 and 9.5 inches. The Bola website led me to the CSR wheel - good looking, good value and should be compatible in an 18inch, but for some reason lkperformance website is listing as non-compatible for a Cerbera.

I had these when I still had my Cerb.
Loved that they looked almost OEM.
everyone else loved them as well.





Oh right they're Enkei PF07's

Really stunning, the colour blends so well with the body. The latest version seems to have an inset on one spoke saying 'performance line' - so design not so pure. I guess these are 18's. Can only find them new from USA - top speed pro 1 performance. 40 offset on rear.

when I ordered them i they had that inset on the picture as well.
But to my relief, when they arrived it was just a sticker supplied in the box.
You can order them from a number of UK suppliers

Here: http://www.vipmotorsport.co.uk/shop-by-brand/Shop-...
Or here https://www.performancealloys.com/wheel-details.as...

The right sizes are 18 Inch 8J 5X114.3 ET35 fronts & 18 Inch 9J 5X114.3 ET40 rears

Thanks Nils

Kind of caught between these and the 17inch TSW's. The latter are a bit cheaper but I would have to get new tyres.
Will post again (may be some time) when new alloys fitted.

Cheers

Went for the rotary forged TSW Bathurst in the end.
Front 17x8 et40 with Yokohama S-Drive AS01 235/40.
Rear 17x9 et40 with Goodyear Eagle F1 255/40.
Pleased with improved handling and grip, still to go for full geo given that I had a steering uj replaced at the same time.

I know you bought the wheels now, I was working where the new wheels would sit with the different offsets.
The wider 9j et40 wheel outer edge is closer to the wheel arch outer lip by 13.35mm rather than closer to the strut. The inner edge of the wheel is virtually in the same place as the original 8.5j et33
Does the new rear wheel just tuck inside the rear arch under load? Any rubbing?

The inner aspect of the wheel is 13.4mm closer to the strut and the outer edge 0.6mm further into the arch, due to the increased offset and as referenced in here
http://www.willtheyfit.com/index.php?width=255&amp...

I believe but can't confirm as tyres came fitted, that the weights are
7.5kg front
and
8.4kg rear
Which is a bonus.

Sorry about that with the offset measurements. I took my figures the wrong side of the wheel centreline. My mistake and sorry if I caused any doubt.

Easily done and wheels can be measured by negative or positive offset which increases the confusion.

Thread resurrection!

I've been looking at wheels for the cerb for years and have decided to take the plunge.
I currently run spiders in the 33/42 offset. You can feel they are heavy and the car crashes about on poor surfaces.
IMO 17" at the front is a better fit than 18" and the above photos bear this out. At the front I run 225/40 tyres and the clearance fore and aft is very tight. Not only that, the steering lock is rubbish with 8.5J ET42 due to the need for lock stops.

18" is the right size for the rear (again, IMO).

My goals are light weight, good looks, better steering lock and cost. In that order smile
The TSW Bathurst are nice wheels and look great, plus they are very light at ~17lb front (7.7kg) and ~19lb rear (8.6kg) https://www.tsw.com/alloy_wheels_bathurst.php
I have some spare spiders in the loft and will get around to weighing them when I get over my bad back, but I think they are 11+ kg.

The wheels I am looking at are the lightest I have found, look good and aren't ruinously expensive - the Weds Sport TC105X Titan (titanium colour):

https://papasmith.co.uk/shop/weds-sport-tc105x-ej-...

As always, the offsets on offer aren't ideal so some compromise is needed. The combo I am looking at is 17x8 ET38 (or 32) and 18x9.5 ET45. One needs to go to 18x9 or above to get the deeper dish profile. Otherwise there is 18x8.5 ET32 for the rear.

The fronts are listed at 6.96kg and the rears 7.95kg. Obviously small weight savings can be wiped out by tyre choice but I want to fit PS4s having read a lot about them.

Total cost roughly £2k for the 4, and should save around 15kg of unsprung weight overall, not to mention significant moment of inertia.

The Enkei RPF1 is also a consideration but a little heavier and not quite as easy on the eye.

What do people think, will 9.5 ET45 rub the inner rear wheel well? The outside face of the wheel should be roughly the same as the ET33 8.5J spiders.
Also would you go 38 or 32 offset for the front? I'm tempted by 32 as my 42 offset 8.5 spiders are well inset into the arch, but am wary of too much scrub radius (reducing the wheel size also increases this a little). The SP12s are 8x18 ET35..

That's a good thread Rog thumbup

Here's one that last 3 Years !laugh

Personally speaking, I don't like the modern fashion of 2x5 spoke pattern so your selection doesn't go with me.
I stioll love the Bolas but are way out of my budget.

I have never known a car turn is an well as the e42 8.5s on my 4.5 so, using the excuse of "If it ain't broke, don't fix it" then I'll leave well alone for the mo'

BUT

We desperately need a good wheel reconditioning service.
So if you, or any of the other contributors, can recommend one, then I would be internally grateful thumbup

I know what you mean, Paul, I am not a huge fan of the paired spoke design, either. But the pairing is very subtle with the weds wheels (it is only apparent to me by looking at the hub) - more subtle than the TSWs above and I think they look pretty cool.

Turn-in is governed by geometry rather than weight. Handling, ride and performance can only improve with lighter wheels. But probably the 38 offset would be better for the front and still allow me to remove the lock stops smile.

What’s the standard wheel width and offset without stops on the steering lock?

The simple answer is get a set of 17" RL7's, (I know that you cannot get them new). They are the best looking wheel for a Cerb and with a, decent set of tyres (Federal 595 RSR's) the car drives great on them.

Don't you have a set of mythical 18" RL7s?

For a 17x8 I'd definitely go ET32

The 15kg of unsprung weight is very significant and you will really notice how well it rides and handles with that!
