Autocrossing a Taycan CT

[ebarron]

I’ve talked to two different local (to me in Massachusetts) Wheel companies that are well referenced in other forums, and they both indicated they are worried about the RE71’s being to tall in the front on 20x10. They’re only available in 285s. Even then they both said 20x10s would certainly require custom made rims (ET55). 275’s aren’t available in 10”.

@Mizzle51 -> you stayed with stock 9” front wheels. Did you research options and end up there?

Thanks.

I stuck with stock wheel sizes to remain in Street classing for SCCA. I run with 2 SCCA rules based clubs and a Porsche club that uses their own classing. I also have a Map-ev Tune, but can't run that for SCCA club points.

However the Pax in Super Street sucks, I might give up and do EVX soon and get some wider fronts to go square. I just would always come in last with my clubs' XA or XB crowds since they are quite good with built cars.

An update for anyone that might go down a similar path:

I ended up ordering rims and tires from EV Sportsline - They were the only vender I interacted with that would stand behind Taycan J1.2 measurements. For me, that was important. The tires arrived with the wrong TPMS however. (new ones being shipped.)

Very Important. I have Porsche Active Suspension - and this changes the internal geometry (makes more room). The front tires I'm told needed that to make the 285s fit.

Rims:
* 20x10 (+55 Front) & 20x10 (+36 Rear), Cyber Bronze color
* 4 x Potenza RE-71RZ (285/35-20)

I chose not to go with spacers, but you could definitely set these up w/the same rims front and back w/spacers instead and that would make rotation easier.

Tires were like a whole new car for autocross.
