Yep. The early ones overpower the rear wheels. Later ones and competition pack are much better for it but it’s still an engine making a lot low down. Last proper M was the V8 anyway of courseI read ages ago the m3 and m4 had quite spikey power delivery on the standard cars. People had better traction after a remap
The only LSD I'd fit would be a wavetrac but it's mega money with my setup.
