These wheel centers are amazing. Woodman sells them too. That's the exact BBS wheel center model i wanted... can't afford them. Chris M (his rennlist call sign) got a set... i'm jealous.

WAY overpriced (for a used set of dubious quality) and the wrong spacing.

I have a set of forgelines and a set of Jongbloeds. The Jongbloeds are sooo much lighter than the Forgelines. I think the weight really makes a difference. Get the lightest you can find that meet your needs and budget.
I like the one piece wheels also but not too many makers out there.

Fred - what brand did you get? Sounds like your are not happy, why?

Bill Verburg

Forgelines are a great wheel and available in custom o/s(I have a set too) but afaik they don't make 15s

The only 15 that I've seen w/ custom o/s is Work

Gary R.

Jongbloed makes them Bill, and the price is fair for the supreme quality of the product.

I have a few sets of BBS/Mahle 15x 9 with 2mm offset that worked ok with 245/45/15, would sell one set.

Actually, those 275/35s seem to provide an advantage at tracks where long legs are important. At LRP and Summit they didn't help so much this year... at the Glen and Road America they were wonderful. The form factor allows you to spend more time in 4th and 5th... (was shifting to 5th at the top of the esses at WG mamamia!).

Gary R.

I think it has more to do with the acceleration out of turns (at certain corners on certain tracks) and the RPM drop between gears. Summit Point isn't one that stands out (if you can get you car to shift.. ) but the Glen is for sure...

Mike - if you get a chance please measure the backspace on the 9" wheels you have and let me know.

FredC

Gary, 10 bucks the wheels Mike has are identical to the gold wheels i have...

Not sure about the acceleration being the real benefit after running the set up for a full season... It helps for sure, but what data has shown is more of a benefit beyond 3rd gear. It could be a toss up, but an extra 5mph before braking at the bus stop at the glen is tough to match.

Gary R.

I bet they are also, 5" backspace. I know you have the only RL experience on those wheels Fred (among my friends), I just look at the gearing/acceleration data and it shows that the real advantage is in the reduced RPM drop and closer ratio they give the 3-4-5 shifts. I truly believe that the way our cars accelerate within their rather small powerband is greatly enhanced by the closer ratio. Of course I could be waaaaaay off too!

And i'll bring that 1/2 sawbuck over to you.

FredC

as i said... who knows. You know me enough to not think that i am trying to display pre-eminence here. All i know is that the steeper acceleration profile is great and you can feel it for sure with the butt dyno. But time seems to be found once the car is up to speed and you run out of 4th and then shift to 5th comfortably in the power band... Again, who knows... I guess you'll experience it soon enough

Gary R.

You display plenty on the track my good friend and that's all that matters.... and as I have never shifted my car into 5th gear, even to see if it exists, I can't wait to see it next April!

For me, they would be a great advantage at Lime Rock as I have a 7:31(?) R & P (and different gears?), so I'm between 3rd and 4th coming out of the three fast corners. I think the 275/35/15 would allow me to hold 4th and be in the meat of the torque range instead of bogging or doing an extra shift. The SCs are probably fine in 3rd, as your 3rd is longer.

The offset on these BBs is only 2mm, about 5" backspacing, so they stick out 1/2" more than my Fuchs 9x16 which have a nice 15mm offset and 5.5" backspacing. But they give you a NICE wide track so if they fit they'd be awesome. Did someone try Fred's wheels with the 275/35?

FredC

smells like tepid mildew once you shift to 5th gear after all these years of not doing it...

I believe that the 9 inch 911 wide body wheels were -3et and the early offset 911 and 944's work with a +15 offset using the 275/35-15's.

I have strained my capacities(mental) as well about the high speed advantage of the 15's and it might be partly attributable to the car being so much lower that it aids the areo on the long straights. Opinions?
