What are the largest rims you can run on a cerbera without fouling the arches?

Without fouling arches or without ruining handling and looks :-)

Do 19" really ruin the handling? What issues do you face running them opposed to 18"

18" is max. You will need to modify the arches for 19s.

Go above 18" you'll get bad tramlining

But you'll be able to fit neon lights underneath the car.

You could run 19's on 255/30/19 tyres and 225/30/19 this would keep the rolling radius very close.http://www.alloywheels.com/tyrecalc.asp

Full lock on the fronts is where you will run into problems, you can trim the Fibreglass back, i saw one done at Power with 19's.
i personally would like more width so the thing will turn in on track!

Lock stops solve that problem! About £3 iirc. Always run 235/ i do on mine with no issues and it's running close though i'm on 17" RL7'S

Lock stops do not solve a problem IMHO

The 19s on mine actually give a better tramlining condition over the 18s I think partly due to the higher offset I'm running on the front.

Rears needed both outer arches cutting back and skimming with FG to stop rubbing.

Fronts required the front and rear of the arches cutting and moving to allow the tyres not to foul (however this was made probably made worse by the higher offset).

I suspect most of my issues are due to the ride height I run, it's low but not ridiculous. It'll still get round the 'ring at it's current height.

Every car I've owned, the first thing I want to do is put a set of nice alloys on them. The cars always look better.
I;ve never done it, or wanted to do it, on the Cerb. The Cerb is a 'real' performance car. If 19", or 18", wheels improved the handling of the car, I'd be tempted, but they don't, they do just the opposite. so why bother. whats the point?

People are different? laugh

I have different sets of wheels for different uses. 19s for plodding around roads and attending events, 18s for the track (although thinking of changing these for 17s).

I'd prefer 16s for the track but they won't fit over the 6 bolt front calipers.

I happily run 16" wheels (Oz Saturns) over 6 bolt callipers. There is a bit under 1/4" of room to spare. I find that they are a huge improvement on track.

Really??? Hmm, I'm sure when I tried this they would not fit at all. How odd.

Who's got a 16" wheel I can borrow????? smile

someone shoot me down here...but my understanding is 16's will only fit 4.2 calipers and NOT the 4.5

Sure. If you want to come up to Brands Hatch - you are welcome to try one.

That may be your understanding however I have 6 bolt callipers from a 4.5 on my 4.2 and have been running on 16" Oz Saturns for a year or so.

Having said that - in order to put the larger disks and 6 bolt callipers on my car I had to make up custom spacers for the callipers. I suppose that is possibly why the rims fit on mine and maybe not on a standard 4.5 setup.

If you want to run 16s then it might be interesting to see how much you would need to change the spacers by to allow them to fit. Making the spacers was fairly trivial.

I have 235/17 on SP's on my front trackday rims, and 18x10" rear (more options), i have witness marks where they have rubbed a little, but thats the beauty of Fibreglass, it machines itself!!

I have 275/35-18 rear road tyres now i have trimmed the inner arch.

Ahhh, that'll be it then. It was very close when I tried so I guess your spacers may bring the caliper in ever so slightly.

The improvement in handling on 16" rims would make it well worth making some spacers so they will fit IMHO
