Another wheel question

[Lemon]

Hello

Well another wheel question again and one I have probably asked before[].

My car originally had Forged CS Wheels 7.5 x 16 ET 65 and 9 x 16 ET 60.

I have seen some 7.5 x 18 ET50 and 9 x 18 ET52.

Now these would mean the front wheel would have 15mm more clearance to the front strut housing and stick out 15mm more, the rears 8mm more clearance.

Now I guess the rears would not affect handling much, but would shifting the front wheels out 15mm change things drastically. Would I then need to re do the Geometry etc?

Cheers

Lee

The forged CS wheels are 7" at the front. I'd have the geo re-done at the next opportunity in your position.

mmm mine say 7.5 on the inside face I am sure.

I would be interested to see a pic if that's the case, I understand 7.5" forged CS rims are very rare.

They are off my Turbo S ( or silver rose ) which I am sure where 7.5"...

I will take another peek at them in the garage in the week. Too dark and cold outside now.[]

I too had the same original wheels and have moved over to the same 18 inch spec with no probs.

Hi Rich

Did you have the geometry re done, or was it a straight swap?

Notice any difference in driving chracteristics?

Positive or negative?

Cheers

Much - much harder ride than on 16's.

Hi Rich

Did you need your geometry adjusting going from 16" to the 18's?

I will be going from 17" 968 Cups 2's if I go for the 18"

Thanks

It definately needed it on mine.

18s are really "tart" wheels on the 944 - they look good but the spoil the chassis a little. Don't get me wrong; I have a set and they were my everyday wheels for a lot of miles, but they are too big for the car from a dynamic perspective.

I'd say you will definitely need the geo redone, but you should have it checked periodically anyway (annually I in fact I think). It will probably go off more quickly on 18s as the suspension will get thumped hard by bumps.

Just what are you trying to say...??![]

You will find the ride much crashier due to the increased wheel weight and the reduced tyre sidewall depth and if you have not yet fitted the 968 lower arm castor mounts, then I would get that done before changing wheels.

Fen is right in that, ideally I would like my car on 17" Cup 1s from a dynamic perspective, but being such a "tart", I really do love the stance when lowered over nice 18" rims....[8|][]

rears 8mm more clearance.

Another 30mm Lee and it will be fine []

When I spaced my rears out the tram lining reduced and the steering felt more positive so I did not feel I needed a realignment.

I'm looking for a set of 16s now to see if the improved ride and handling are worth taking my 18s off for, the 18 inch wheels may not be the reason but I find when really pressing on down a bumpy back road I'm running a bit wide on the tight corners.

That was exactly what 18s did on my cab, but the coupe with the stiffer shell shouldn't suffer especially. If I were you I'd borrow 16s, but if you want to drop back from 18s then I'd sugges 17s as a compromise between looks and performance.

I include myself as a tart by the way, hence running the 18s for a long time.

Yep 17 inch cups would look nice but they seem to be loads of money, I'll keep a watch on ebay for some and the originals too.
