I need to get new front tires for an upcoming track event this weekend, unfortunately, I can not get new S02s to me by then. Local Discount Tire has Kuhmo Ectras, I know these are popular alternatives - would this work with my S02's on the rear? Will the car exhibit more understeer/oversteer etc..? What should I look out for?

Thanks for any responses.

 

more understeer. They would be less grippy than stock.

If you care at all about your perfomance at the track you should invest in 4 of the same tires.

 

possibly try S03 all the way around.

 

I put my rears on 3k miles ago and they are good.. how much understeer?
I plan on going S03s all around when I'm out with my rears, I just can't throw away good tires..

Thanks for the responses.

 

Paul it will push but ........ you know ..... just drive it

 

It's never a good idea to mix and match tires, especially if you'll be driving at the track. Not only the compounds are different, break-away characteristics are different too. You are more likely to get yourself in trouble, unless you're an experienced track driver who enjoys the added challenge.

 

Personally? I wouldn't. The 712s aren't as good as the OEM tires, no, so you will notice a performance drop. Plus, the mix and match thing isn't good, probably especially since you've got two different-sized tires on that car...
