SFR has been very good for the small but popular products i've ordered; but, if they don't have what you want and place it on backorder, i think that's where the issues lie. As for the VHR kit, i can't comment but it is what SFR uses in their drag i4.
Besides that I would make sure you change your flywheel also. I understand it is alot of money (so was mine) but you need to wrap your head around the thought. Besides, you already know what a cheap POS clutch and flywheel are like; you claimed to of have one for 86xxx miles LOL, Do both clutch and flywheel so that you don't have the same woes with the tibby in the premature future.
