A7 vs R7
 

Maybe I'm searching wrong...but do our cars prefer the Hoosier R7 or A7 for HPDE duty? 3100lbs, 275 tire. Camber is maxed out at 3+° front and 2° rear.

You'll need Mor camber first Hoosiers. And ambient/track temp and number of laps will determine which tire you need.

Are you going for 1-2 fast laps, or for consistent performance across 20 minute sessions?

Ya R's for DE duty, A's for the money shot because you'll roast em typically. For me it's a super fine balance - I have to have them for the starts because EVERYBODY is on them and it's a real PITA to catch them back up on certain tracks due to R's taking 2 laps to come into temp. But after the 6th or so lap they start to cry about it so you have to back off and watch your mirrors for half a lap, race a lap, back off again. Endless. So now we're trying to go WIDE to help the situation. Something many others have proven works but time and money and time and money.

How wide are you going?

Going from 275's to 295's to start. I'm going to have a ton of bodywork trimming before I jump again to 315's. Dallas keeps trying to get me to slam the thing but I'm already "tucked" too much as it is lol.

Why run Hoosiers for a non-competitive event?

To ^ point, thought you were selling it even lol.

my adjustments are maxed out. No way to get more with current setup.

275

Purely for fun and a PB before the car goes

Enjoying it until the day I have cash in my hand.

Since going for a PB: warm up then a couple Time Attack laps. I guess that answers my question LOL
Assuming a warm A7 grips better than a warm R7.

Just don't break it lol

Depends. A's will always grip 3x better on a sticker vs sticker setup. Usually 1 warm up, 1 money shot, 1 cool down. The 2nd 10/10ths lap will be slower since they are overheating at that point and your just wasting them. Also the "sticker" lap is going to be the fastest, then everything else will be slower and slower on a steep decline.

R7's will plateau after the sticker laps for about 6 heat cycles, then go slower and slower.

So if your plan is to register for a weekend and do 3 laps and park it, then go for the A's. But I'd have a second set of track tires to continue enjoying the weekend since that's your plan. Mama never said going fast was cheap lol.

Car's built to take a beating. She's all good :D

If that's the case, since I'm not racing for trophies, I think the R7 would be a better tire. It'll be faster than my NT01s, I assume, so all good.
