The MBX-6 is a great car, I love the new captured cvd pins. I have read that if you do a lot jumping the alu front tower is a must, I got it with the used roller I bought.
I think mike's kit for it looks good too, and one could easily make mek. brakes for it as well. I am glad I chose tekno, even though I had some problems with heat in the clutch at first. If you are going to use the clutch, get some softer alu shoes or carbon shoes and thin/slightly bent out springs. The stock shoes are too hard imo, and start slipping too much when hot.
I wholeheartedly recomend the MMPro and tekin 1400kv, a perfect setup for these cars

A medusa 1300kv works very well with the MMPro too.
