Hi guys, let me explain the pricing.
An upgrade from stage 2 to stage 2+ is priced at £795.00+VAT.
On a stage 2+ upgrade, the build is treated as if it were a fresh build, with all new bearings, any rebuilder parts, plus a gearset that we have shot peened and polished. But you are effectively supplying the Quaife ATB diff that already belongs to you.
The value that we apply to that diff is £400.00, which is the difference in price between a stage 1 box (£495.00) and a stage 2 box (£895.00) with the difference between the two boxes being the Quaife diff.
You might notice that at £400.00, that is quite a discount over Quaife's £475.00 retail, but I buy in bulk and pass some of that discount on.
So, the upgrade works out to be a stage 2+ box at £1195.00 minus the £400.00 for your diff which gives the £795.00+VAT.
Hope that explains ok
