Can we see more than just the wheel. :rolleyes:

A lsd will mak any set up under steer more, the higher the lockup % the more effect it has, thats why, for a mostly street driven car 40% is as high as I would want.

An even better setup is a split 40/60 lsd

Your right, when the trans was apart I had it set up at 60% thinking I would do more track time but it turns out It's alot more steet time. I can only imagin what the early turbo drivers felt when the got on it out of a short freeway sweeper....anybody still out there who can comment on the 75/76 turbo with LSD... not the 4-way/windowpane

For a Turbo. These are significantly heavier in the rear the a narrow body car that most are changing to. Still works but I like more rubber up front to match the 245.

Ahhh, that's what I was looking for ..an opinion based on having tried it. Thanks, Jack!

Thanks for all the chiming in. Obviously I'd *like* to have 9s for the aforementioned advantages, but if there's no significant *felt* benefit (at my skill level, anyhow), then I'll stop dreaming and budget for other goodies. Thanks, all!

Ahhhh ..... Bill V... do you want to rethink your answer about wider rear track will increase oversteer?

You are the admitted Grand Master on brakes and wheels.....but think this one through once more....

Wil :)

Yes, I meant to say wider rear track will increase understeer

If you're gonna run 8s and 9s, why wouldn't you just use 225 and 255 tires?

Depends on which wheel diameter you're talking about.

16's are not readily available in a 255 section width that's the appropriate size. The most common size is 255/50 which is an inch taller than appropriate. More common rear sizes are 245/45 and 245/50. The 245/45 is the right size for our application. Front choices for 225 front are 225/50 or 225/45. The 45's are usually the better choice to avoid clearance problems (shorter OD), but not as readily available as the 225/50

17's are plentiful in 225 and 255 section widths. Typical sizes are 225/45 front and 255/40 rear. Or 235/40 front and 255/40 rear, 275/40 rear. Or 245/45 front and 275/40 rear. As you can see, the choices for 17's are much broader.

Kevin it right on. IMHO the perfect wheel tire setup for a 911 narrow body is 225/45/16 on 8" 951 offsets front and 245/45/16 on 9" turbo rims rear. (of course this is what I run, so I'm biased:D )

89911 : I'd love to see the 8s at the front. Pics please - PICS !!!

Here's a thread that shows 951 8's on the front of 911s:

Just to add to Kevin's and 89911's comments

Unless you regear the transmission you will want to stay close to the factory design height for the tires which is ~25" &#177

Doesn't matter whether the wheels are 16, 17 or 18", when the tire height or more specifically the loaded rolling radius(which is generally not published) is increased, bag things happen to the overall gearing and percieved performance of the car.

There are good reasons to go to taller tires for a specific track, but not for overall general use.
