RUF 19" on '99 C2
Hi guys,
First off, I'm new to the P-car thing ither then my '72 911e. Second, I'm sure that this has been answered a zillion times BUT....
I have a 1999 C2 Aero Kit car that I would like to get 19" Ruf wheels for. I am ready to order with tires but need to know proper sizing/offset and tire size. I'm running 265/35/18 Rear and 225/40/18 Front right now.
Also, was thinking of the H&R springs but is 1.25" too low? This is not a track car but more a daily toy.
Any help would be greatly appreciated!!!!
I look forward to visiting with you guys often and hope that I will be able to help the 'new guy' one day !!!

I see in your photos (yep, I was snooping) that you have the set up that I want. I got a reply from eBay seller that these wheels are too wide for the back of a narrow body car.

19's are pretty big for a 996 and might cause faster wear of the suspension components,
also using the HR springs without matching shocks can apparently cause problems.. I wanted to do the same thing, but now have rethought and will wait until i can do it right.. :-)

I have to agree with bk. 19" are pretty snug + you want to lower? I think some guys here have done it. Wouldn't do it if you want to track it now and than. I have the stock 18's and like them. Would like a different style but still 18"s.

Somewhere I've read that Porsche DO NOT recommend 19" or larger rims on 99 & 01's - something to do with the underbody support has to have bracing installed (which Porsche did at some point mid year 01). The lower profile add's just enough extra grip (lack of tire wall flex) that it transfers through to the body when the suspension max's out. One would assume that they have to take into account that some people will be tracking their cars so they plan for worst case.
A couple of things to think about: 1. Unless you go for a super light weight rim - sometimes going up in rim size add's unsprung weight to the car which is normally not what people are looking for when they buy larger rims. All things being equal, larger equals more material unless you change the amount of material (by a lot) or the 'type' of material. You may not care and only are going for the 'look'.
2. Your shock package (unless you changed/mod'ed them) was designed for the 18" and a little extra 'spring' in the side walls. While 18 to 19 isn't a big change for the street - it could be on the track. If you don't track your car I guess this isn't much of an issue.
3. I would think about this 19" upgrade from the stand point of your shocks, sway bars and drop links etc. Quite frankly a lot changed on 1999's as the 'standard' tire was 17" and the "upgrade" was 18"'s. Unless your prepared to go whole hog and look at the whole package - bolting on a set of 19's (it's a given you get the right offset) without at least looking at how everything ties together under your car - just makes good sense to me. And ask about the bracing - maybe it's a part swap or there is a bolt in solution?
4. You may find that you cannot get a proper rear alignment with the 19" with your 99 OEM rear suspension. You may end up with GT3 parts just to get the proper settings as there may not be enough adjustment. I know just lowering the car get’s you into this territory of ‘adjustability’ as I’m running into that with my (to be installed Apr 2011) upgraded springs. I'm not an expert but these are things you need to ask a good Indy or Dealer about before you drop some big bucks for new rims somewhere and you show up with them to have them installed and you see the alignment guy walking towards you from across the shop floor with a frown on his forehead after he’s spent a half hour on your car…. Just saying.
Cheers.

Any other opinions?

I run 19's with 67 offset R and 51 or 55 F and HR's I get some rubbing in front on the wheel well liner at full lock so as long as l don't do donuts all the time I am ok.

I'll post pictures if I go ahead with it. I sources 67et & 55et only ten hours from my front door. Brand new for $1200Canadian shipping included. Repros of course but why the hell not for that kind of money?!
I'll go with 295/30rear and 235/35front.
Hope to have pics up soon!

I have had 19' RUF's on my 2002 Carrera for years. I run their suggested sizes 235/30ZR19 and 315/25ZR19. I even use their 7mm spacers on all corners and have no issues.
The car is setup to its highest setting using RUF's coilover kit which are rebranded H&R's for the C2. They now use Bilstein for all their suspension kits.
