GT RADIAL - CHAMPIRO SX2 reviews

On MAY 4th having a time attack event in MIMC go-kart track. My current tyre are wear out, so i have to looking tire to change. Recently i have heard about the GT RADIAL brand tires on CHAMPIRO SX2 series has alot good reviews. Traction , wear&tear and handling are good... So i give it a try on these tire.

As below are the picture of the actual tire of CHAMPIRO SX2  tread-wear 200 size i choose is 195-50-15. 

the Water trade design are good~ and the compound design look good too.

Before the time attack event ,i has changed 4pcs of CHAMPIRO SX2 for my car. 

After changing tires i tested on wet road condition, its perform very well compare with my previous Nankang NS-2R. 

After time attack event, the result of the tires performance are:
a) side wall too soft, effect the stability of vehicle during cornering.
b) delaying of response during cornering.

TOUGE up hill tested, the result of the tires performance are:
a) need to keep counter steering during exit the corner.

After the time attack event, 2 weeks later MIMC open track day. I have joined to try again with these tires.
After few laps, the result tested. The stability of vehicle while exit the corner keep under-steer until out of the track.

haih~~ push too hard.. hit the stone and the sidewall air leak~  

above pictures are the 2 front tires of CHAMPIRO SX2 sidewall bang the rock and sidewall crack, and another 1 can see the inner structure of the tires~ so 2 of these tires BYE BYE end of theirs life~ T.T
