17 inch wheels, 7.5J front 9J rear, ET40 front and rear.

My plan is to try and find and RUF speedline style wheel but slightly updated for the 996.
Just because I happen to have been down this particular rabbit hole.

Speedlines ? Not light as I understand it, but strong

I like these but I've spent too much time thinking about 17s and convincing myself that it's the right thing to do (for me) not bail on the idea.

Which is why I'm going to go for these in 17s, with customised offsets.

Is there a wider rear option?

I was looking at some pics of one of those restomod 964 which had 17 inch wheels. The rears looked fat. I zoomed in on the pics and I think the rears wore 275 40 17 tyres. I'd guess that's probably a 10 inch rim. If you're thinking of 225 or even 235 fronts on 7.5 then the 275 rears may work better.

Available in widths from 7.5”-12” in 18”, so I’d imagine also available in a 17” variant.
The issue will then be tyre choice though possibly.

I've decided to go full tarts boudoir for the wheels on the GT3.9



They arrive Monday. I think I can get away with it :hehe; Plenty of coloured wheels in the past but I won't lie, that as in my thirties and when I didn't give a stuff! I had considered re-painting the centres gold but it would then just look like every other black 996 GT3.

They may need to go silver.

Nice wheels, but £568 a corner? And I assume more for wider fittings and custom off sets

Will be a £3k set of wheels yikes

One more; ubiquitous.

Although I suspect it simple to answer "well there's a reason for that"!

I think they're OZ. And really heavy. And priced by weight! Reassuringly expensive.

Well, if you’re not wanting the ubiquitous look, leave them red …
And as you’ve already got that Fokker DR1 biplane wing manacled on the back, you may as well paint its end plates red along with your mirror caps.

Highgate House will do you GT3 side decals in red too cool

hehe that’s what my mate reckons as well, get the side decals to match.

I do have unnatural thoughts about doing my own take on the Stefan Johansson art car…

Good question. I could go for wider rears, but after watching this video by {{url=thethrottlecable}https://www.youtube.com/watch?v=iyZIx9Z2r-I{/url}} i thought I'd go for slimmer rears.

He talks about the rears on his GT3 being overtyred for the road. My car is never going to see a track. It'll get more power but probably no more than around 350bhp at some point, and I do want the car to feel alive on the road.

I also spoke to Centre Gravity and they recommended mirroring the 964RS set up which is 7.5 front, 9 rear.

Since you bring it up I'll give it some more thought and i'll try to figure out what the offset will be for a 10J, and this case I'd go to 8J on the front.

I'm all about slimmer is better in terms of width. But I thought I was in the minority. I'm also about fatter is better in terms of tyre wall thickness.

The standard 17 setup is 205 50 front and 255 40 rear. I might experiment with a 245 45 rear but doubt I'll notice much difference. Was also toying with the idea of a 215 45 front.

Or just to be awkward, the early 964 Cup cars used 17” diameter wheels, a 9.5” rear and an 8” front.

I used to own a (admittedly rather lovely macademia over cocoa) 997.2 Carrera 2S. I think that had 11J rears so I do have my own point of reference, and it was nowhere near as nice to drive as my 996, for the type of driving I do.

I'm all about the sidewall. I like it from an aesthetic perspective, probably because my first toy cars were a couple of nascar style muscle cars that my mum bought for me from woolworths. I'm also 40 years old, and I've become very sensitive to ride quality and road noise. I just want to be comfy all the time and have accepted that I most enjoy driving at about 6/10ths, so I don't need that extra body control.

Interesting about the early Cup RS, but because I'm lazy I think I'm going to stick to the 7.5/9 specs....for now.

Since you bring it up I'll give it some more thought and i'll try to figure out what the offset will be for a 10J, and this case I'd go to 8J on the front.
The notion that reducing the front wheel width by half an inch and reducing the tyre section by 10mm, is going to drastically transform the 996 from something with a preponderance of front end grip and inert steering, into something with tactile, engaging, talkative steering such as that found in an early pre-impact bumper 911, is to put it mildly, fanciful.

Likewise reducing the rear wheel width by an inch and the rear tyre section by 30mm won’t enable “supermarket trolley with a jammed rear caster” levels of oversteer at any and every opportunity.

If you’re chasing an improvement in ride quality through taller tyre sidewalls, or a “look” courtesy of the 17” wheels and the chunkier sidewalls, fair enough, but be aware the 17” tyre sidewalls have to do the same job (support the car’s weight) so whilst they may be taller, they won’t be drastically softer, and any improvement in ride comfort will be as much a result of downspeccing the tyre, ie going from an 18” Cup 2 to a 17” PS4 will automatically improve ride comfort.

So unless you specifically want the 17” “look” I’d stick with 18” wheels, more comfort biased 225/265 tyres, and play with the tyre pressures and get the geometry tweaked to make the car more agile.
It’ll work out considerably cheaper than a set of custom 17” wheels and tyres…

The lower you go exacerbates the wheel disappearing into the arch.
The lower you go, the more negative camber you gain, which in turn makes the wheel look more inset from the wheel arch.

Thank you for your thoughts. If I went with 18s I would go for:

8/10, with ET35/50.

mr. slippydiff, whilst I have your attention I recall you have some experience with 996 GT3s. I am currently on the lookout for a 996.1 or ideally .2 gearbox. If you were in my position, who would you speak to, to source one?

18s with +15 offsets would look like this.
