A second set of M6 wheels is a good solution :M5thumbs:I know many people on here have fitted after-market wheels and some of them really do look very good but I don't think I'd ever put anything other than OEM M5 or M6 wheels on my car.
At the end of last year I put several bids in on a set of genuine M6 wheels for my car and was going to keep my standard M5 wheels for track days/winter driving with specific tyres on. Unfortunately I was outbid but am always on the hunt for another set.
I was going to suggest something somewhat similar. If you are considering spending that much money on wheels, have a custom set of 18" wheels made for the track, which will allow you to use a much wider variety of track tires. A 18" wheel can be made without having to change the brakes, and it should cost you much less than a set of Needz.Another consideration is to "upgrade" the brakes to a BBK system, but with a smaller rotor diameter so you could fit 18" wheels. Your selection of tires would increase dramatically.
See you at Silverstone, I've also reserved a garage for the day, as I thought it may rain...Nathan, I think you're car looks great with the M6 wheels and if I was in your situation I'd simply get a nice lightweight (dymag) set of 19's with some good rubber for your track days (but I don't want you flying past me on the corners at Silverstone GP.:trophy_bronze:..yes I'm about to book it :1
Of all the ones you've listed, my preference, if any, for daily driver wheels would be towards the RAC R4's or the AC Schnitzer type 5 but the latter look too similar to M6 wheels IMO.
If you stick with the M6 wheels for daily driver then go for the ultra light dymags for the track but at the end of the day it's your choice.
PS - if you decide to get rid of your M6 wheels I might be interested.
Issue with Neez is getting them in the UK and importing them makes them 17.5% more expensive and at that price I'd just buy the dymags.I think the Dymag's would be overkill for our car. Definitely worth the money, however if you're going that route it would make more sense to put them on a dedicated track car or some sort instead of a 4000lb sedan.
You can see if the make they Neez Eurocross European Rim. That's the version of the Eurocross with no lip. Those are lighter than the QD7's.

This is something that I have not considered, an 18" wheel.I was going to suggest something somewhat similar.

If you go 18's with the wheels, you could have a dedicated track wheel and stick some Michelin Pilot Sport Cup's on or some R-comps. If you do eventually want to run R-comps, I suggest just biting the bullet earlier and get a BBK kit that is 18" wheel friendly. I think brakes will fry pretty fast when they try to slow a heavy car with racing tires.This is something that I have not considered, an 18" wheel.
does anyone have any details on the clearance that is needed, ie, the internal diameter?
I do believe that some people have checked the clearance on 18's you can buy off the shelf and you can get wheels to fit, but the clearance is very tight.
An 18" dymag, hummmm
Tyre choice is improving for the 19's, Pirelli Corsa system, soon Toyo R888 and I believe Hoosiers, but the choice of 18's is much greater and also cheaper.

Yes the 19's or 18's would be just for the track.If you go 18's with the wheels, you could have a dedicated track wheel and stick some Michelin Pilot Sport Cup's on or some R-comps.

I received an email from Toyo saying additional sizes for the R888 will be released in early 2008, I've just sent the guy another email to try and get a date. With the new tyres it will be possible to go with.Guys --
(1) If the R888s will be available in a 19" size that fits our stock wheels, by all means use them. That is what I am using on my M3 track car, and they are excellent.
Is that going to be too narrow for a 10" rear rim?Guys --
(2) MPSCs already are available in 265/30/19, and can be used all around on the stock wheels. I have done so with good results on the track (you can find my threads on this topic). 265 is borderline too narrow on the rear, making them not ideal, but they do work.
I've not really had a problem with the stock brakes, I know that some people have posted saying they are terrible, but that is not my experience, I've only ever once had my pedal go "slightly" spongy.(3) Don't mess with the stock calipers or rotors. We already have a BBK -- the front rotors are 14.7"!!! Dave Zeckhausen, among others, will tell you that this car does not need an aftermarket BBK, and I would not get one if it decreases the rotor size. The limiting factor in braking performance is tires, not the brakes. For example, the biggest difference you will notice with R-comp tires like MPSCs is the improvement in braking, even more than cornering, which itself is a huge improvement.
(4) Get Pagid RS19 front/RS14 rear brake pads, make sure you bed them in properly, and you will have all the braking you need. I used this combination with MPSCs and had a great time.
(5) Replace the stock brake fluid with a high performance fluid -- at least the ATE Superblue. Cheap but very effective and important so you do not boil the fluid. You should flush your brake fluid before a track day anyway.
A BBK would be beneficial for a few reasons. If you go with a rotor diameter the same or smaller than stock, you'll most likely reduce both sprung and unsprung weight assuming you get floating rotors. The new rotors would also run cooler. The new calipers would likely have 4-6 pistons which would apply more even pressure when compared to the stock 2-piston design, which should result in better pad wear.I've also asked dymag about some potential issues with an 18" rim, but I am concerned that if I go to 18's and then feel I need to get a BBK, I can't unless I change the wheels.
The brakes are great but brake fade is not the same for all drivers or tracks, as it can depend on driving style and the track itself and the thought of spending that kind of money on wheels only to then need largers ones is really the only thing that is holding me back. But the choice in 18 inch tyres is so much better.
I think I may be worry too much about both issues, 18's will probably be fine and April is not far away to be able to run R888's front and rear on 19's
Going with a smaller rotor and expecting it to run cooler does not make sense to me. The larger the rotor surface area, the more easily will the heat dissipate. The stock rotors are drilled too. Will a 4- or 6- piston rotor apply more force? Perhaps, but, again, the limiting force is the tires, not the stock brakes. The stock brakes already apply enough force to easily trigger ABS. I am not suggesting that an aftermarket kit is a bad idea, just that it is hard for me to see the cost benefit given the expense and the performance of the stock brakes.
