Ive driven the lx's occasionally, mainly offline for fear of what i would do to people online lol. I have to say i like both equally for differenr reason's
LX4 - Alot of fun, quite stable but still with a tendancy to oversteer.
LX6 - Not so much fun as it's a beast, but i like that it's a beast make each lap fun.
Our team server (or servers last night) have been set to LRF BL1r in the lead upto the BOTT race and there have been quite a few people on with a few driving the lx6.
