If I may ask for a bit of input please ...

I will be running the full seasion of auto-X and will have a 2nd set of tires / wheels.
I will ALSO be doing some track days ...

So in researching tires I have some options and now questions

I am 99% sure that I will get Tracklite v2 on a 17 x 8
MUST have 17s (Iknow not the best choice for auti-x BUT I have BIG Brakes)

want to run 235/40-17
I am very modified / cut wheel wells

tires;
Kumho v710 are used in both auto-X and track, the auto-X guys try to keep heat IN the tires as these work better hot (not much selection in 17" size)

Hoosiers have a A and a R compound
A= Auto-x ... work well almost cold but would overheat on track ? and not last long at all.

R= Race /track and need heat (so is this the same compound as the Kuhmos?

Then the new BFGs R1 is also a single compound so again like the Kuhmo need some heat for Auto-x

any thoughts

If you help me find wheels and tires at a GREAT price I'll "hook you up"

 

Be careful with V710 on the track. I destroyed a set of fronts at a track day at Carolina Motorsports Park. Great for a club race, but would get kind of expensive very quickly for regular non competitive track days.

Be careful with brake pads also. A pad that works well cold for autocross probably won't be able to take track temps, and one that works well at track temps won't be grippy enough cold for autocross. Edit: Just noticed that you have big brakes, so my issues with stock brakes may not apply to you.

I ran Hawk HP+ for autocross with no problem for two years. One track day had them delaminated, crumbled and melted.

But these are probably extreme examples, since I'm not too gentle on my equipment.

I think you are going to have a very difficult time picking one tire that is a top notch autox tire and also suitable for track days.

 

The A compound Hoosiers wouldn't last long on a track, while the R compound wouldn't work well on a short auto-x run. The Nitto NT01's are an affordable compromise for track work....perhaps run three sets (much cheaper than Hoosiers and a MINI friendly size)? Street, auto-x and track? I don't think there's a magic bullet here.

I'm running RE01R's....great for street/auto-x, but wouldn't handle extended track sessions due to having tread.

 

the bfg R1's are the only ones in a 235/40/17. these are just slightly less expensive than the Hoosier R6's (available in 225/40/17). both of these are primarily track tires.

the khumo V710 might be your best choice of compound. Several MINI drivers have won SCCA national championships w/ them. i have a buddy that uses them on road courses and likes them. this is his first set, so i cannot comment on how they wear. 225/45/17's are about an inch taller, so effective gearing will be higher.....

good luck.

 

Thanks to all for the info ...

Yes I know I am looking for a magic set up.

I do have 3 brake pad compounds for the Willwoods so that shouldn't be an issue

So it really looks like 3 sets of TIRES !!!

The 235/40 BFG R1 is only 24.2" the 215/45 KDWs that are my street tire is 24.6

 

I think three sets is really your best bet also. I've been using the Nitto Nt's on the track for the past year and i like them. I also used them on the pseudo-Auto-X i did and they didn't heat up until to late.

 

a contact at Hoosier just emailed me ... maybe a set of As and Rs is in my future

 

that sounds like the best case. i don't autocross, but i like the R6's. they don't wear great, but grip is awesome. i'd like to try the bfg's in 235.40.17. does anyone know of a light weight wheel in 17 x 8. i might have kodiak make me a set.....

 

you can get the 17 x 8 in the Tracklite v2 now ...
Can you rell me a bit about Kodiak (my son wants to do 15 x 10 !!!)

 

i learned about Kodiak from RSR. they can do a 15 x 10. or about anything else you can imagine. check out their website http://www.kodiakracingwheels.com/

not cheap, but less expensive than my HRE street wheels (by a large margin).

custom is the way to go. you get exactly what you want/need.

 

It does sound like 3 sets of wheels/tires for ya!

There really isn't a good 'top tier' r-comp that will do both AX and track well - there are plenty of '2nd tier' r-comps that will do what you're looking for, though (e.g. Toyo RA-1). Of course, you give up a 'considerable amount' of time running AX on RA-1's ('considerable amount' being significant if you're uber-competitive in AX).

If you're uber-competitive in AX, you'll definitely want a top tier made-for- AX'ing r-comp tire... For DE's and track days, though, I'd still probably go with RA-1's - you'll get a whole lot more life out of them than you would with Hoosier R's.

Of course, if money's no object, go HooHoo all the way!

 

I used to run Kumho VictoRacers on my 944T at the track for track days and even won a few NASA time trials, Hoosiers are definately faster though, but the Kumhos lasted a lot longer and if you're not trying to win anything, why waste time and money? Actually using slippery tires on track days makes you faster when you drive on stickies in races! Turbos suk at autocrossing so I didn't do much then, but when I ran the CP Mustang (way bak in the 90's) it was hoosier race slicks! Luckily, our local region of SCCA and another Indy Autocross club runs classes for "street tires" > 100 tread wear. I'm thinking Falken Azenis for triple duty on my new 2007 MC. I'll try the new guy out over at BeaveRun track days again as well.

 

Azenis are a good triple duty tire, but also check out the Hankook RS2 z212. The Azenis heat up faster than the Hankooks, but the Hankooks handle high heat better. So, the Azenis are a better autocross tire, but the Hankooks are a better track tire.

 

I've got an almost new set of RE01R in 215/45/17 for sale. It's winter here....I'll buy another set in the spring

 

Nice choice of rims, you gonna stick with black wheels on your car?
