I read many of the archived threads but never got a firm answer.

I am purchasing some A032R's for track use only, so no street driving. Will I want the S or the H compound?

Also, I will heat cycle them, but is shaving neccessary?

And I have heard that driving 50 or so miles on the highway is a "cheap" alternative to heat cycling, is this a true fact?

Thanks in advance,
Marshall

How long do you want them to last? H's are awesome for longevity but the S' will have more adhesion

unless you are racing - don't bother with the shaving

yes - get them warm then let them cool down completely

Thanks.

As for longetivity, I want them to last at least one year, which consists of about 6-8 lapping days, with ~3-4hrs of total on-track lapping time each day.

So would I benefit then from shaving the tires? Does this increase the life? Or just traction...? Assuming I use them for the sole purpose of track events.

About how long would a good highway drive be for a complete heat cycle. I am driving down to Portland for a race day the 26th, but that is almost 200 miles. If I use that highway time (from Seattle to Portland) for a heat cycle, will that be 'too much'?

Sorry for all the n00b questions, these are my first set of R-compounds.

 

Shaving just gets you to the optimal tread depth for racing - not necessary for you. It will decrease the life of the tires. On "unshaved" (is that a word?) tires - You may find the tread "squirms" a bit when they are new - but that's ok - you should give yourself some time to get used to the much higher grip levels these tires will give you. Then - as they wear down - you will find the traction gets better and better.

3-4 HOURS/per track event is A LOT! I usually get 4-5 20 minute sessions and that really works the tires good. I would definitely suggest the H compound if you intend to use them that much. Most SCCA races are &lt;1 hr - what you will be doing is equivalent to endurance racing/driving which is the H compound is a better choice for.

Your drive to Portland will be perfect - PIR is a great track with lots of flat runoff areas - just keep off the back wall ok?

If you look in the RoadRace/AutoX forum - JohnG has posted some good in-car video of RR98ITR (Scott) doing laps there during Rose Cup. Scott knows the track very well and the videos show you the ideal race line.

BTW - A032Rs hum like a **** on the highway. You might want to get some earplugs. Just a suggestion.

Looks....... Fast

Don't shave the tires unless competiting to win. Open track days are meant to be fun, safe days. No reason to waste money by shaving tires to be a little faster. After a few events you'll be at optimal treads depth anyways, and will be a better drive anyways.

I suggest breaking teh tires in a bit before going to the track. That was you wont get new tread slippage. 200 easy street miles with a good normal camber will wear the factory gun off just nicely

 

Thanks all.

I go in for another alignment tuesday, so I'll make sure to have them camber it a little more even than my last alignment (I had them set it up for track use before).

PIR is a fast track. I'm expecting to see 170ish in the supra and 140 in the teg, gear limited of course

I'm hoping to see a big difference between the RE-010's and the A032R's...BIG...

Definately no shaving if it just means I get to the meat of the tire quicker...screw that.

Well, I think I got the info I was looking for, thanks guys.
