I've done hours.... no, DAYS of research and sent out dozens of emails to various vendors..... and all I've done is gotten myself more confused (and ended up down rabbit holes about the physics of traction v. friction in regard to tire construction.)

The car: 2020 M2C w/ Carbahn flash. Call it ~550hp/565tq. WOT in 1-2-3 essentially guarantees repeated DSC events. I want to mitigate this.

Please, to the experts here-- WILL THIS SETUP WORK WITHOUT RUBBING?

Wheels: Apex EC-7 (F:19x9.5 ET28 & R:19x10.5 ET45). Wheels are 0.5" wider than stock w/ "M2C-specific offsets". Stock offsets are ET29 and ET40.

Tires: Michelin MP4S 265/30/19 & 295/30/19. Stock tires are Michelin PSS 245/35/19 & 265/30/19.

Suspension: TC Kline Single-Adjustable Front, Double-Adjustable rear coilover suspension w/ 300/600 VVS springs & TC Kline camber plates set for Street. The springs on this setup are not conical like the MPS or Litchfield so the springs/struts should be very similar dimensionally to stock.

Suspension drop: Planned to be no more than 1/2 - 3/4".

I do not want to use spacers (required w/ Apex wheels and MPS suspension), nor excessive negative camber where the wheel is obviously tilted, and am attempting to get better low-speed street compliance, a minor aesthetic drop, and better traction to prevent DSC intervention. With no rubbing.

My thoughts on the larger rubber are for better traction, but maybe I'm heading in the wrong direction? Would 255/275 be a better choice?

Other possibilities:

1. 255/35/19 & 275/35/19 on stock wheels w/ TCK suspension. (Not much wider than stock, slightly taller).

2. 255/35/19 & 275/35/19 on Apex wheels w/ TCK suspension. (Not much wider than stock, slightly taller-- but tire height may be mitigated by 0.5" wider rims? Unknown. Not sure of any traction improvements?)

3. 265/30/19 & 295/35/19 on stock wheels w/ TCK suspension. (265 at the limits of fit for 9" front wheel, 295 over the limits of fit for 10" rear wheel by 10mm).

Help? Pretty please? I've just gotten myself into "paralysis by analysis" and I need to start putting parts on order.

TIA--

See my answers in the other thread I replied to you.

Now I know who tuned the car. You need boost reduction in the first two gears, at least. 540bhp full go in first is a waste of time. Only good for putting down long 11's : or lighting up the sash with the DSC light

As I have mentioned in the other thread. Running stock sizes/stickier tyres and boost reduction in 1st & 2nd I had very little issue with DSC interference.

Adding massive amounts of wider rubber is adding weight too and in the worst place to add weight.
