RE: XXX-S or TT01???
TT-01 for Drift and keep the Xray for Racing
The TT-01 was Bornb to Slide so let it be free..
TT-01 is also a little more Durable to gutter bashes .. the Belt system on the X-ray, while better then most can still be ruined by the smallest of pebbles..
use the TT-01 for drift.. with an Alloy Propshaft and bearing kit, you will be suprised at its Drift ability..
