This is strictly autoX question. I will not use V700 for HPDE/track, so please keep that in mind.

What should I be concerned with, when I switch from street tires to Kumho V700 tires? (Aside from obvious "more grip, less warning before the tires break traction.")

Set up will be:
1. 15x7" wheels
2. Lowdowns (2f/5r)
3. 23mm r-sway

I'm not in DS anymore due to gutted rear & the above listed items. I am not competitive in SM due to lack of power mods, I can't be in STX due to the interior & tires. I autoX to get my 3 minutes of GFCP every few weeks.

1. Anything thing that I should be aware about V700?
2. What tires pressures for f & r tires?
3. Does the driving style need to be change w/ R-compound tires?

2. What tires pressures for f & r tires?
cold: 38~40F & 40~45R is what I used

3. Does the driving style need to be change w/ R-compound tires?
not really style, but just remember j00 can brake WAY later and take the slaloms much faster

 

If you put the rear interior back in, you can stay in street prepared.

 

Trust Me, Words of wisdom.

Learn to drive the snot out of your car well before you go to R compounds. I know this all too well since I went to R compounds almost virtually after my 2nd autocross event.

Needless to say, I am back on street tires albeit Azenis but, I am relearning what I missed and learning faster and am able to lay down some very decent times as compared to my R compound clad peers.

I am almost ready to jump back up for R's for Both Autocross and Trackday's but, I do this for fun and I'm not trying to push and theres no reason for me to spend more $$$ right now, besides rodney has my wheels

If you are ready then absolutely R compounds are an awesome difference, and if you want to be competitive they are the make or break for winning positions. I'm personally just in no rush anymore and have modified my learning curve to better fit track driving,,, and doing just fine.

Plus, it's sometimes just totally satisfying to arrive and sip coffee and watch everyone else swap tires after doing it so many times in all sorts of conditions before.

Pressures will be a trial and error thing and will vary with the weather conditions and track temperatures as well as driving style, as I'm sure you are aware of and will get a varying array of settings and pressures posted here.

Good luck and let us know how it goes. to R compound's...

 

I have V700 225/45/15 mounted all around on 15X7 Kosei's

My favorite tire press settings are 38psi Front/ 33psi Rear

This gives me anything I want (understeer/neutral/oversteer) with proper use of throttle and brake.

I too am no longer D-stock.
