I am looking to purchase wheels/tires for the upcoming DE season. I have a 2005 997S. I plan to run 18" wheels with Michelin Pilot Sport Cups. Between the BBS LM and the RS-GT, is one a better wheel than the other for this use? Also, would 8 1/2" fronts offer any advantage than the stock 8" wheel width on the fronts? Thanks in advance for your help.

Hello!

Afaik, the LM-rim is a bit lighter than the RS-GT. In my opinion, the LM also looks better. But that depends on your personal taste.

You could use 8,5" in the Front with 225s or 235s. I wouldn't use wider Tyres on 8,5s because of the traction. You don't want the car to understeer, do you?

Thanks for the info. I haven't had a problem with understeer - the car has plenty of power to kick the rear end out.

Actually, the RSGT's are 1 lb lighter each wheel than the LM's. I have both.

actually a wider front tire will reduce understeer

I've got 8.5 x 18 et50 rims on my 2000 S Boxster with 245/35 Dunlop SSR's. The SSR's run about a size wider, so they are more like a 255 in width. No rubbing and the traction is outstanding.

Thanks, yes they are. The finish is gunmetal. Just to be complete, the rears are 10.5 x18 et40.

law,

The 8.5s should work fine. They will be just slightly heavier than an 8 inch wide wheel, but not by very much.

I use the BBS RS GT's as "track wheels" on my 986.

No complaints.....they are light, strong and look good.

I would say neither and suggest an alternative. There are better options that can get you the fitting you want and save you some money. I recently made had the same dilemma. I just got a custom made set of 3-piece Classic race wheels from CCW (Complete Custom Wheel, www.ccwheel.com). I wanted an extra inch of rim width front and rear (18x9.0"/18x11.0" wheels) and had a hard time finding this application for a reasonable price. A quick call to John at CCW was the answer. I am running GT3-sized Sport Cups (235/40 and 295/30) tires on the wider wheels. CCW custom makes every set like Fikse, Forgeline, etc. The difference is John at CCW has always geared his business for the racers at a more reasonable price. CCW is very well known in the racing communities and has a great reputation in the autocrossing and road racing communities. These wheels run $2000 a set for 18"s or about half the price of other 3-piece wheels or those BBS LM's. I went with a set of the clear annodized (light gray) centers since he already had them made. The wheels were complete and shipped 2 days after placing the order. I would image for a 997 with the wider bodywork that John could do a set of 18x9.0"/18x12.0" with the right offsets to fit. You should be able to run 235/40 and 315/30 tires on that setup.
