New wheels

Very nice 👍

what size are they 19?

And how does the ride feel over lumps and bumps and how’s tramlining from the chamber of the roads on these?

i have 17 cup 1,s on my turbo and I would have loved to go larger but wanted the best of both as I’ve read if you go any bigger than the 16s and all starts to go downhill regarding handling , ride comfort , and tramlining.

i admit my 17’s are 255/45 at the rear and 215 at the front and I do feel it tramline depending on the road which has stopped me thinking of going any further regarding diameter.

they look lovely though mate and really complement the Car. Mines the same colour red also 😊

Hi the wheels are Compomotive M06 18” with 10” on rear and 8” on front tyres Mich super sport front 215 40 18 and rear 255 35 18, much to my surprise the car drives and rides better than it did with the 16’s tram-lining slightly but not to bad at all. I have bought the Renn line 968 uprated castor blocks and plan to fully re bush the front end.

 
I've never had tram-lining on 18's with 225 and 265 tyres, have you checked the alignment? I'll concede there's a little more weight to the steering and the lower profile tyres have less give in them though. How much do you want for the old 16's?

 
Sorry not for me. The earlier CS ones looked much much better. Equally a decent set of CS wheels will pay for your new wheels and tyres these days.

30 year old wheels of unknown provenance for the price of quality new wheels and tyres, not for me thanks.

 
So any idea what the CS wheels are worth? They are all in very good condition with new tyres, metal centre caps need redone.

 
A 944 with properly "tight" suspension should always tramline a little bit, even with the standard 16" wheels. Mine did and does more so since I fitted 17" wheels, so if you tell us the difference isn't that big I would think there might be quite a bit of looseness somewhere in your front axle and/or steering...?

Not a fan of the new wheels either, but beyond the look they may be a lot heavier than the originals and affect the handling accordingly.

 
TBH I wasn’t really planning to sell them, they are genuine Porsche wheels from a Turbo S, very light weight, also told they are quite rare Silver Rose wheels? 16” 9” rears and 7” front tyres fitted are 225 50 16 front and 245 45 16” rear I think? The Rear tyres are

Brand new fitted last year for MOT with full thread- Nankangs (not my choice) the fronts are also full thread also a budget tyre but in perfect condition.

 
I have a set of CS wheels for my turbo s which are not going anywhere as they are original fitment,I run 17" Cup 1's, my CS wheels have had a refurb but NO machining as this will take too much metal off losing some detail and can render the wheels dangerous, do NOT have them machined.

if they already have been done they may be scrap.

I like the look of the 18" on yours but I suspect the car would be a much nimbler drive on the originals.

This is on a Power steering car though which masks and isolates what your asking the car to do (Deal with heavier and wider rims / tyres)

which also changes the front scrub angle radius, camber arc and kills performance (Adds time to 0-60 acceleration times etc..) puts more strain and work on the dampers, springs, brakes and bushes etc..

If the rack was manual you'd notice a massive (Adverse) difference and the car would be so much more difficult to drive, if like some it's lowered also this makes a bigger diameter / larger rim width setup

handle even worst because the car's roll (axis) centre angle will make it tip worst than a standard ride height.

This car's original design Geometry (Zero Scrub Radius) is only on the 924, as every other evolution (after the base model) had a wider track (early and late 44's and 68) and hence does not handle

the same because the strut angle is (bigger) jacked further out at the bottom stub axle point with longer lateral wishbones, this encourages tramlining on road contours and cambers.

Hence the 924 narrow chassis does not tramline like the wider tracked models do.

Well, my "hideous" boot spoiler is at least a (very) rare original part [:)]

And it will add performance NOT make it worst like fitting heavier wheels.

Is there any end to this drivel.

I don't think many places anodise the CS wheels to give the correct original finish.

No due to their age, especially if corroded etc...unless they are re-machined to clean the metal to regain the

polished look from the refraction of light in-between the machining channels they will look awful.

So in light of NOT machining them to reduce the strength, they can only be painted and this is obviously not as original,

but there's nothing that can be done due to their age and this rarer anodised finish. So owners either leave them as is original

but not the best, or have them not original but the whole rim painted in a silver etc..

The facts will never go away !, and are to be recognised for some that understand them but not for others that don't or don't

want to etc..

Just pointing that for those they say there's not much or any difference it's because of the power steering which assists & masks

a heavier wheel change which would be so much more apparent on a manual rack.
