All these items precisely installed and tested by Birds in the UK and shipped out to HP Auto in the USA and then re-shipped to the customer (or directly swapped by you at your site)... is that right?
Is the supplied final drive somehow "shorter" than the original 135i one?
Thanks, Karlenstein

A brand new BMW final drive from the 335i(most 135i ring gears are welded) is used for the Quaife Final Drive build.
In some cases we use a low mileage final drive when available and the price will be lower.
Either 3.08 or 3.46 can be build depends on your application and use. If you have a manual(3..08), you can step up to the 3.46 for faster acceleration.
Since no ring gear modification is needed(bolted final drive from the 335i). Everything is installed here in the USA and tested.
