What color are those wheels? I'm looking to get the same pair / set-up on my 718 GTSFinally got my track wheels and rubber; (center caps not yet installed) View attachment 23698
What I went with:
- Wheels - Titan 7 TS-5
18" x 9" ET46 front; 18" x 10" ET35 rear.
These are a fully forged wheel (not flow formed) and very strong.
I tracked a set of these on my E92 M3 and they were flawless.
I usually use most of the track available including curbing when feasible and never had any issues with bent or broken wheels..
More info here on the Titan 7s. ......and here
- Tires - Hankook RS-4
18" 255/35 front; 18" 285/35 rear
I've used these tires before and am very happy with them.
RE-71R may be a tick faster (also used them before), but the RS-4s last WAY longer and are much better bang for the buck IMO.
the tire wheel combo diameters are slightly less than 1.5" compared to stock 20"
20" front = 26.48; 18" front = 25.03
20" rear = 27.30; 18" rear = 25.85
The important thing here is both front and rear are reduced in diameter by the same amount, so that the rake of the underfloor is maintained, plus all the car electronics/nannies are kept happy.
Some advantages to the smaller package.
- lower rear diameter reduces the overall final gearing. (shorter final drive)
This gives you a little more punch when getting back on the throttle.
- the car sits approx. .75" lower (I'm already on SPASM)
This does a couple of things; lowers CofG and should also increase the velocity of air under the car for more downforce.
