When limited slip units are not serviced before end of life of the clutches, damage can occur to pressure surfaces (ramps) touching the clutches. Great news is that we offer a service to exchange for good condition ones! This set is factory 45/45 ramps found in most BMW 188mm LSD units.
While returning a core set of ramps is no longer not necessary, if you send us a refurbishable set of ramps, we will issue a $175 refund.
To return a set of ramps for a refund, follow these instructions:
- Ramp set must be suitable for recycling into this program.
- Securely package the ramps along with a copy of the original order invoice and ship via USPS small flat-rate box to: Thayer Motorsports, PO Box 1453, Ashland, VA 23005.
- USPS is the only acceptable shipping vendor for core returns. The required USPS small flat-rate box is very cost effective. Confirm your shipment is appropriately insured and tracked before sending - we are not responsible for lost or damaged packages.
- Once inspected by a member of our staff, a refund will be generated to the original method of payment.
