Restart10 Gen3
Lightweight Smart Battery
by Litemax

I seek to find ways to reduce the weight of my E92 M3 without compromising its street driving characteristics.

I believe BMW M cars need a smart diet.

BMW M adopted the lithium battery on the F8x as they pushed to reduce weight on an ever bigger M3.

We can retrofit this newer technology into our older Exx M chassis.

It is one of the best bang for your buck upgrade for weight reduction.
