Can you track down some hollow spoke 18s like I had on my car?

I'm sure I could but not sure I want to. The 997 18 inch are reasonably light I believe but I've not had them off. The 996 17 and 18 are all seriously heavy. I'm leaning towards some 17 from the 987 range. They seem cheap enough for a suck it and see trial.

They look ok. I'm less interested in how the car looks and more interested in how it drives. I can't believe how much grip there is and that's with these not so great tyres. I'm toying with the idea of going down to some narrower 17 inch wheels. The car was originally spec'ed by Porsche with some very narrow 17 inch. Maybe less is more?

According to the below link:

Front
17x7
205/50/17

Rear
17x8.5
225/45/17

Be careful, sometimes uprated suspension doesn't work well with tall sidewalls. The car may start to bounce noticeably on the tyre and work the damper less. This feels sh!t and lessens grip too.

Ok thanks. How would I know if this is happening?

The guy I bought the car off said it came with r888 tyres and he changed to the tyres on there now. Do r888 tyres have stiffer sidewalls?

Mine came on my 996 and I didn't even realize they were hollow castings until I took them for a refurb.

Picking them up (even compared to other, smaller, wheels) and they were massively lighter.

I am still not convinced you want to go for smaller diameter and larger sidewalls as it will affect the damping.

However, if 17s (and tyres) are 'cheap' (or could be moved on for next to no loss) then the 'effect' could be beneficial as you may prefer more movement and a bit softer.

I used to run R888s and I actually didn't think the sidewalls were that stiff, for a 'track' tyre.

The effect is pretty noticeable, especially in pitching front to back.

Vertically stiffer sidewalls will help, I know nothing about the r888. Personally I think a nice sports Michelin with a 35 to 40 sidewall is a wonderful thing.

My beast [e46] came with semi slicks. It had 225 40 front and 255 35 rear. They were Nankank NS-2R front and Federal RSR rear. Once I had them removed I could feel the Nankangs were very heavy and very stiff. The tyre guys showed me on their machine too. The Federal were much lighter and softer.

Anyway I switched to a square setup on the beast so 225 40 all round because I picked up some light OZ wheels which were the same width all round. The car still behaved fine and I couldn't really detect a loss in acceleration.

Watch the offset if you get 987 wheels.

Too low?

The wheels are 18 from the 997 base model.

Fair point! The perils of posting on the hoof. I think 18s are the biggest I'd go on a 996 but it's not my car Looking forward to seeing where you go with it as it seems like a really nice base for something very "PH" (not that he standard car is anything but PH in my view!)

You can check the offsets using this as a guide http://www.944racing.de/felgengewichte.php generally Boxster rear wheel in particular have a different offset to 911.

As you can see there there's loads of stuff you can do to modify your car but most mods, generalising a bit, make the car less compliant and more focussed towards more grip/better handling/higher corner speed. Best bet is to get comfortable with the car, get comfortbale with what you think you want to spend, figure out where you want to go then double it

The big ticket stuff you seem to have covered in suspension. Engine doesn't seem to be an issue for you so pointless looking at throttle body and plenum etc. Brakes as you've found out when working well with fresh pads and fluid do the job on the road amazingly well. It feels like damping adjustments and revisiting the geo might be worth looking at.

Interesting RE: weight of tyres. I have always thought a stiff sidewall is preferable for track-biased tyres?

In terms of a) performance b) durability c) value for money, what's your view/preference between 595RSR, NS2R, AD08R? I can get all theses for 996 sizes.

I only had my other car with the 595RSR rear and NS2R front combo for a little while. The 595RSR were a bit worn and went in the bin. The NS2R I still have. I even bought a new set of 595RSR in 265 35 18 but didn't use them as the trial fit showed they would rub. I still have these and could put them on the 911 I guess.

The weight difference was noticeable. I could be tempted to try the NS2R again but I would probably plump for the softer compound because why not right?

A. I cant really give you a performance assessment because i didn't really use them much and had nothing to compare them against.

B. I've seen some internet rumours about the 595RSR coming apart or developing a line across the tread which is concerning.

C. The cheaper tyres are 75 - 85 per corner. That feels like throw away money to me.

What 996 have you got and what tyres have you got now?

Cheers.

Mine is 996.1 C2 with M030. Currently with P-Zero but will need replacing soon. I do have a second set of wheels with Bridgestone S02A (N4), these are second-handed, came with the wheels.

I have used 595RSR before (track and road) in my other car and also have a set NS2R. NS2R used to be very cheap but price has pretty much caught up with 595RSR. AD08R are not much dearer so they are currently my first choice to replace the P-Zero.

N-rated police will be along shortly to tell me that I'm DIW.

This thread is giving serious want for a nicely sorted 996.....!

Keep the updates rolling OP.

This and poppopbangbang's thread and I'm looking. I've even got wife approval on the finances.

OK

So my 90's porn star porsche has needed coolant top ups on more than one occasion. It also has a definite clicking noise coming from the back which is related to engine speed. I can definitely see a damp patch on the road under the engine so hopefully my car is losing water rather than using it and this all adds up to a new water pump. So she is going into a Porsche specialist tomorrow for a check up.
