Default Watsons + Metro GTi wheels - Clubman arch options

OK, I've done a little searching but there's too many arch related threads


I need some nuggets of wisdom from those who've walked this path before... I have a watsons frame B16 currently fitted with ET 7 minilights and STUPID wide arches. I'm about to swap over to MGF hubs, brakes etc and some 7 spoke metro Gti wheels. I therefore need to get rid of my silly arches and replace them with something more sensible.

I wouldn't mind a small cheeky tyre protrusion and I'd prefer a rounded style as opposed to a straight miglia style. Any suggestions please?

Cheers Oz.

Am I right in thinking they're both 3 & 3/4" wide?

I'll be getting FG or carbon ones seeing as I'm on a FG flip front. Any suggestions on where to go or equally, where to avoid going?

Both are 3.5" wide IIRC, either would cover a Metro 7 spoke with a 175 section tyre from the random photos I've seen of cars with them fitted.

I can't really recommend any to go for or avoid. I think the 16v Mini Club gets a discount with ABS motorsport

I've gone the Watsons route and quite happy with it - except for the DTA ecu. They sent me a set of 7 spoke MPI GTi wheels which are 5.5 x 13, have +52 ET and a pcd of 3 and 3/4 inches. They fit (just) under Sport pack arches at the front. I also used their 100mm spacers at the rear. They bolt to both the hub and the wheel, and fit well inside the Sportpacks. And my engineer is happy with that setup - here in South Aus. I also am replacing the rear rollers with Timken tapers, to manage the extra load better. I looked for AGES but couldn't find a 13" wheel with an ET of +52, regardless of pcd.

Cheers dude, did you go for genuine sportspacks or plug for some copies?

They sent me genuines - secondhand, of course. I replaced some of the screws and a few were missing, but it turned out OK. Maybe worth a call.
I also swapped Metro stuff for MGF - like front bottom arms (changes +ve camber to a bit of -ve), steering column/steering wheel, and rack (faster than Metro and quite workable, and NO bump steer). If you have the DTA and you live up near Liverpool or Preston you should have no problems finding a dyno man who knows how it works. In Australia, NOBODY had heard of it and it cost a LOT to watch a dyno man learning how it worked. Ended up with a good solution though - a tick under 100KW ATW and it pulls really well all the way.

Just a note re the hubs and discs - I stayed with the MPI GTi ones - the vented ones with Green Stuff pads. They worked really well at a local hillclimb. Unless you know the MGF ones are better, and they are needed for track work, you could be spending big for not much return. Also, will they fit under a 13" wheel?

Hubs and discs are the same - just the bottom balljoint is different between Metro GTi and MGF (and only a slight geometry difference, the balljoint architecture is the same too)

Thanks Fynn and pockets.

That's what I thought regarding bottom arms, I've already purchased metro GTI ball joints, top and bottom.

Regarding hubs, brakes etc, AFAIK, it's the exact set up that was on the metro GTi, so it should, at least in theory, all fit.

I'm looking at doing this job over the next month or so, so hopefully I'll have some actual IRL updates to share soon
