BMW Welded Diff Conversion Kits

‘BMW Welded Diff Conversion Service’ is for customers who want to send us their original open or LSD differential and ring gear only and have us carry out the separation of the factory welded ring gear and differential. We take your supplied welded diff and ring gear, split them and then machine the ring gear to spec, drill and thread the ring gear to accept bolts. After this is complete, you will need to install this into your existing axle, this is a service we can provide at an additional cost.

fast delivery, amazing service

‘’Had a Wavetrac in my MK5 Golf, Alpina B10 and Porsche Cayman S. Just about to fit one to my BMW M3 E92 and will more than likely continue to fit one to every one of my cars. Track day performance is incredible, especially in the wet or on tight tracks. Excellent on my daily Alpina too, rain, ice and snow - it's an all weather machine despite being an automatic BMW!’’
