I added some camber, currently running -4* up front and -2.5* in the rear.

I run mine at 29/27 too, -4.5* camber front and about -2.2* in back.

It's a balance of overworking the shoulder and outright speed. For non-national events I try to run higher pressures to prolong life. Then I get to 3rd runs and I'm like "f*** it" and dump a couple psi to try to win lol.

My co-driver and I had our first event of the season yesterday.

We tried out 9k front, 11k rear springs on the RaceComp Engineering T3s. It worked great.

I had the Karcepts front bar on 0/0 and the rear Mann Engineering bar on medium.

It was about 55 degrees, using AO52 tires on asphalt at a local airport, so pretty smooth tarmac. There was one section that was in a parking lot that had wavy pavement, in a accelerating zone the first day, then a braking zone the second day. Other cars had issues, but our setup worked really well. Inside the car felt good, but outside you could see the oscillating suspension.

Autocross/track toy at the point

FWIW for everyone new to the Yok gain, you have about a 4 PSI range of operating window where the tires don't get any faster or slower yet change the dynamics of the car.

smg1138 · 04-19-2021, 03:57 PM

I'm kind of surprised to see how low you guys are running the A052's. With the soft sidewalls, I figured higher PSI would be needed on those. Good to know though.

Any of you guys running Nankang CR1's this season? A lot of other 200TW tires out of stock right now, so I'm giving them a hard look. Based on the sizes available, I think they're SCCA legal?

Im on the CR1s. Running 30f/28r for my first. I'll try dropping pressures next event.

I've been down and not able to travel anywhere the early part of this season, so I've messed up and didn't buy tires.

Not really sure how I'm going to deal with Spring Nats, etc, etc, etc.

The tire supply shortage is quite serious now for autocross tires. I was told Monday that if you don't have a set of AO52's now,you won't be getting any before September. Time to track down some Kumho's, Nankang's, Falkens, BFG's. Running lesser tires for local events to preserve our national event tires.

I was told more in the 2-3 month range, but who knows.

I could skip locals and make my set from last year last that period, but I'm not super excited about any of the options available.

Did the limited prep DSP thing go through?

PointDSM · 04-21-2021, 11:04 AM

Yes it did, if you have a spare set of Hoosiers, go have fun!

I don't, but if I have to buy a set of tires to not necessarily be competitive, might as well go as fast as I can.
