You probably prefer the hint of understeer (Marina) but not too much (Crows), and maybe don't like a hint of oversteer (Oakland)?

Also, you will then get way more heat in the front tires, and on super hot dunlops, that's just recipe for a bad day.
Hmm... I did also cook the rears. All the tires were purple afterwords.

I guess "all over the place" isn't the right description. The car would just not do what I wanted. It was super annoying. One of the reasons why I wasn't too jazzed about going to Marina in the first place. Hopefully I can eliminate heat problems with a water sprayer this weekend. But I'm not expecting much.

^ Are you using different tire pressures and rebound settings for Marina?

Everything is the same (that's my problem).

Which is what brought up this...

Erik, were you able to compensate enough with just dampening adjustment?

I believe you can run more rebound on those flatter surfaces, but don't quote me on that.

I didn't see it posted. What Gagan said, try more rebound. You may also need to increase tire pressure since there's more grip.

That will sharpen the response, but, will likely build heat faster or when the heat is there the pressures will go way up and then you get even more issues.

Might try lowering pressures and see how it is instead.

^ Maybe. Lower pressures could lead to more rollover, though. He should try both. Either way, he's running the Z2 so he'll need water.

Jourdan, you'll want to have ice cold water, so you'll need lots of ice.

The ice water helped a lot. Much better time than last month.

I also found out that Alvin takes awesome photos.

Sometimes, I love that i-club doesn't re-size images.

^ Of course the water helped, and my best pics have come from Alvin and Jansen.

Yeah...

I didn't have any heat problems last year.
