i just spoke to the guys at Fikse (they are great) and for a price they can reconfigure the rears. it's not cheap. they did note that the fronts should fit but asked if the brake set up on the 996 GT3 was larger then the 997 GT3. i have no idea, any ideas or suggestions on swapping 44 offset 9X18 fronts from a 997 to a 996? Thanks, in advance, i just want to be sure!

There should be absolutely no issue at all in the front. It's the rear you need to be concerned with. Forgot to ask but are the wheels local to you that you could try them out first? If so, do they come with tires and what size?

ssort

no, not local. no tires. i'd start from scratch on that aspect. Fikse would charge 800 to reconfigure the rears. i'm in seattle so no freight to them and back. in the end the selling price has to be right, we'll see.

thanks for all your help!

LVDell

$800 is nothing if they price is right like you said. I have run several size tires and wheels on my GT3 and the 11" rear (63 offset) with a 315/30 tire is about as tight to the outer fender as you care to go. You could steal a couple more mm but it's just not worth the potential tire cutting that could happen.

Keep us posted!

CCW manufactures forged track wheels for Porsche and other cars. Their typical 996 GT3 setup supplied for track setup is 18x9 front, 51mm offset, and 18x12 rear, 64mm offset.

Victor Equipment Porsche Wheels application guide reads like this:

MODEL TYPE YEAR CHASIS WHEEL STYLE FRONT REAR
911 Carrera 1998-2004 996 LeMans, Turismo 18x8 (ET45) 18x11 (ET52)
LeMans, Turismo 19x8 (ET45) 19x11 (ET52)
Zehn 18x8 (ET45) 18x11 (ET55)
Zehn 19x8 (ET45) 19x11 (ET55)

MODEL TYPE YEAR CHASIS WHEEL STYLE FRONT REAR
911 GT3 1999-2005 996 LeMans, Turismo 18x8 (ET45) 18x11 (ET25)
LeMans, Turismo 19x8 (ET45) 19x11 (ET25)

which have even less offset in the rear.

I assume these must be a set of used wheels you're looking at. If you're really interested in them and they are close enough, see if you can mount them on your car first. That's if they have tires, of course.
I don't think you'll have any problems with them.

LVDell

First of all, I'm not going to even get into the CCW issue. I still am baffled why they suggest 12" rears on the GT3. There's a reason (that i have already stated) why the offset is 64 on the 12" wheel. They are not needed for a GT3 and further, are built for a 335 rear tire. Talk about overkill.

Not sure where you are getting your application data from (Victor) but the 11" et25 is insane! That's a 38mm outward push (over 1.5 inches!) Their is info is clearly wrong.....absurdly wrong. Right down to going smaller in front at 8".

Why try to put a round peg in a square hole?

Steve B in SD

all he wanted to know if the 18x11 et 51 rears would work. That's it.
Answer: Yes they will.
It's the same as taking the stock 18x11 et 63 rears, going down to your local Porsche dealer, and buying a set of factory Porsche 17mm spacers for 996NB and bolting them on. (Check with the parts dept. if you wish)

Do that, and you end up with 18x11, et46. Right?

If the result were going to be tragic, would Porsche make and sell the spacers for the car?

Steve B in SD

and yes, 64mm offset is needed for a 12" rear, again, being the same as (outboard side) an 11" rear with
the 51mm offset.
CCW makes very high quality track wheels. They've sold many sets in that configuration for some reason.
If you put a 335 on the rim, it may rub. With 315's however, they are fine.

LVDell

Sure, they will FIT. But will the fit PROPERLY? Absolutely not. And to bolt a 17mm spacer is once again WRONG! And no, they are NOT made for the 996NB with stock wheels. Tragic? Absolutely not. Just take a look at the pics I posted and you will see what bolting a 17mm spacer would look iike on the stock wheels.

I am not disputing the quality of the CCW wheels but rather their "rec'd" sizing. Sure, you can sell that size but it doesn't make it right. Again, the offset in their 12" wheel is needed for INNER clearance which is NOT what we are discussing.

Trying to explain any further is an exercise in futility. Not quite sure why you are so adamant on your stance. I think the OP has everything he needs to make a decision.

Singing off......

Steve B in SD

I'm only adamant because you're giving him inaccurate info. Yes, the spacers are made for 996NB, believe it or not. Yes, the 12" rears CCW sells are right, like it or not. I have one friend that tracks his 996GT3 with 9's & 12's with 315 hoosiers on the rear. Another with 315 Toyo R888 on the rear. I have 12's with 315 PS2's with street alignment.
We're all "wrong" and you're "right" Doubt it. And, CCW is wrong? Doubt it. Have you ever had 12's on the back of your car? Doubt it.

Please define "properly"... it seems to be a moving target for you. All of these setups work on the street, the track, and spacers made for and supplied by Porsche... and all are "wrong"? You're right?

Gimme a break. Get your info right at least.

LVDell

Steve, show me where I am giving inaccurate info. My info is 100% spot on and accurate. All the "info" you are giving is VARIATIONS off the stock offsets.

Jesus, it's like arguing with a 2 yr old.

At what point did PAG ever release, rec'd, offer, manufacture, etc, etc, etc, a 12" wheel for the 996GT3 let alone the uber agressive offsets you say are accurate.

Again, I never said they would NOT fit. He didn't ask about 19" wheels. He didn't ask what oil is best. He didn't ask what exhaust sounds best on the car. He didn't ask what is the best tire. He asked about the fit! And the bottom line is that the fit is WRONG!

Why do I even try any more?

Steve B in SD

Who cares whether or not PAG rec'd a 12" rim?
Fact is, they work.
You told him the rears are "a deal killer" if I remember correctly.
By that arguement, you told him the fronts were fine.
So, when did PAG ever recommend a 9" front for the GT3, if you're so concerned with a PAG blessing?
if PAG sells spacers under their name from the dealership, isn't that a "blessing" that they work-- if PAG is important to you?
Fact: 18x11 et63 with a 17mm PAG approved spacer, by default, makes a 18x11 et 51 rim fit. Simple math.
Again, that's all he wanted to know.
Technically, the 18x9 et44 rims he's looking at for the front are 997 rims, not 996. But, they will work too!!!

All of us running 12's have "wrong" fitments? Please explain!

19's? oil? exhaust? tires? 2yr old?

Why do you try? Dunno. What you're telling him regarding the wheels he's looking at is flat wrong.

guess you're out of facts?

Unsubscribing.

Tracy, you have my contact info. You are welcome to contact me anytime offline. I don't want your thread to get mucked up with Steve's hellbent effort to rationalize inaccurate information. It's not beneficial to you or anybody else.

Not again...

Ok, Dell is correct on the 11's and their offsets. I use the cup offset and i find it works best for me it's 15mm further outboard. to each his own.

You are correct that a 12 does fit, i recall that you had some HRE 12"s that you were surprised fit considering the offset. That was a couple years ago irrc but the point is you can make things fit with spacers etc

The gentleman asked what the "correct" offset is and was given an answer. Not (unless i read it wrong) how can I make it fit. If Fikse will change the offset for him great, and they know what the correct one is as that is their business.

we all need to chill, this economy has everyone up in a tizzy

SSORT:

If you're really wanting to buy the wheels, as the owner to do one thing.
Fikse doesn't manufacture wheels using "offset" anyway. They (like many others) use backspacing.
Offset is a calculation, backspacing is a measurement.
Have the guy measure the backspacing on the rear rims.
If they are 11" rims with a minimum of 8" backspacing, they will work.
Or, if you have the serial numbers from the wheels, (which Fikse wheels generally have) they should be able to tell you what the backspacing is. My guess is they will tell you they are 8" backspacing.

Not meaning to discredit Dell in any way, believe me. He's a very knowledgeable guy. However in the case of GT3 wheel fitments, and the advice he's purporting re spacers, PAG recommendations, CCW recommendations etc., he's speaking from theoretical, not experience.
