Those widebody 964s all appear to have 18" wheels. Many think that is sacrilege on older models don't they? I think they look fine, but I'm interested in people's thoughts because I have 16" wheels on my 1972 replica of a 1975 RSR IROC and finding replacement tyres is very difficult.

I would stick with the smaller wheel especially if you like to drive your car..IMO the 18 “ wheels only look great on instagram

Fit 15 in,plenty of tyres about,if 18 in,you need a proper set up to work correctly.

Slippy that blue wide body looks the mutts nuts,not generally a 964 fan,but!

[ChrisW.]

I think the olive green car looks rather tasty ... I had an Exige in the same colour ...



It had less than 1000 miles on it and I had to go around checking the tightness of the fixings on it ... washers are rarely supposed to rattle !!

Yes they do look the danglies where appropriate

I suppose my point is on most mere mortal 911’s the ride is adversely affected by fitting oversized wheels. I’m all for a bit of subtle customisation but Porsche rarely got it wrong especially on the earlier cars.

[964Cup]

For 18s to work on a 964, IMO, you need to update the suspension. Mine is now on KW V3 and it's night and day compared to the stock (admittedly also tired) setup. The stock suspension, also IMO, works best on 16s even though everyone fits 17" Cups (and, NB, that's what a Cup car should be running, although mine was on 18" OZs when I raced it).

[ChrisW.]

I think that the 17" wheels on the RS worked well but it's interesting that I found the 964 Cup front dampers were much more effective than the standard front dampers even on the road ...

Effective as in a little more responsive to the road surface and yet more damped when worked hard ... agreed that KW's can give you all of this.

For serious track work fast bump is essential ... IMHO.

As for profile, of course the tyre wall is a component of the overall suspension but the structure also has a big effect. Run flat tyres were notoriously hard whilst the "pattern" Michelin XWX tyres on my '73 2.4S seem to find every excuse to wander ...

The manufacturers of Blockley tyres suggest that this due to the ply structures and materials ... claiming that theirs are far better in this respect despite having the same profile and width.

Either way, I have £1300 worth of Michelins on the car and the suspension / geometry is completely standard and checked to be working well.

Maybe I have just got too used to 20" rims and 35 profile tyres with modern dampers ??

It's an utterly hideous colour but a good platform for a project I reckon

I believe the Uniroyal Rainsport are the usual tyres for the 16 inch D90's. Generally reckoned to be quite good. Can't say I liked them that much. I could feel the flex of the tyre wall in the bends. (Or was I imagining it?)

Now running 17'' Rufs which I prefer. Don't think I'd like 18s.
I do like seeing a 964 with the original D90s though, which I think are underappreciated. The Design 92's have become a bit too commonplace.

[GTRene]

came across this one today for sale, looks good with some nice details.











this one could be a more 'normal' price in the end, not say 3-400k and or double such

That looks fabulous.

What is the light dial thing?

[GTRene]

I have no idea, they used partly new instruments I guess because of that engine see the km tacho, but that red light thing?
first I thought maybe a red shiftlight, but in the picture it stands stil so I guess not, I also guess its not a alarm light, maybe a open door light?

I also think it does not really fit there, I guess the builder has a reason for it, but what? I'm curious as wel.

I just asked that question to the owner on his ad page, maybe a answer tomorrow :-)

Love the colour.

I do wonder about these resto/hot rods with the massive wheels on them….absolutely no need on modern rubber for wheels that size to cope with 300 bhp. All that weight in the worst place possible….dread to think what the steering is like.

As it is an RSR replica it surely 'needs' wide tyres to reproduce the original look? The original RSR would have been @ 260mm section on the rear, but tyre availability is pretty poor if you want road legal ones. My car has 315 section at the rear on 16" rims, which I agree are on the large side, but i don't seem to have much choice. If I was to change to 15" wheels the usual choice seems to be to go even wider at 335mm!!!. I'd love to hear people's thoughts on options because I don't want to use the tyres that I currently have.

[Cleanhands]

The old Evo magazine comparing the ten best 911s (issue 36) said that the '74 3.0 RS had already lost some of the handling purity of the previous year's RS with it's bigger wheels and tyres. Looks wise, I still prefer it.

Sorry if this is a stupid question, or it's previously been asked, but if you took an Impact bumper car and made it look like a '74 RS is that a backdate, or is it only long hoods that count?

Surely that is a tanning lamp, no??

Nice looking car,description is a tribute which is fair enough as its nothing like a rsr.
rsr,s shoe horned as big a tyre as possible under the arches in period and now.It would look daft with narrow tyres on, the grip generated with rsr width tires and wheels will blow a skinny tyred car into the weeds,it depends what you want out of the car.
335 will work well if you have the bhp and set up to work the tires ,plus you will need wider front tires to balance the car up,and of course the clearance.
Keep on enjoying the air cooled.
