Its fair to say we must have replaced more accumulators that most people out there so its a been a bit of a passion of ours to come up with a better solution than OEM and their limited life, although changing them every 5 years or isnt awful the fact that McLaren keep putting the prices up is and we are all about keeping McLaren ownership as cost effective as possible. Our new accumulator has been designed to do exactly that. We dont like using the P1 accumulator as it wasnt designed for the chassis weight or the suspension used on the 650.
Central to the product is the retention of the internal diaphragm design which we feel is essential to maintain the ride comfort from the suspension, the issue with the OEM versions is that this diaphragm is too thin so eventually splits so ours is much thicker so retains the function but is significantly more long lasting, ours all have a 2 year, unlimited mileage warranty. Ride comfort is identical to OEM as if you were using brand new accumulators.
Price is for a single unit, you need to replace all 4 on the car at the same time (unless changing shocks which come with them fitted)
