how much did hydro dipping the diffuser cost?
It was £50 for the dip.
I've not updated this in a while, mainly because not a lot has changed. I've been spending most of the time replacing OEM parts for maintenance stuff really & generally trying not to spend much money on the car.
So... I made it to the ring in September, managed 5 laps over 2 days and the car went really well, I was impressed with the PS3's and generally had a trouble free trip.

Unfortunately my GoPro mount that I had on the dash decided to 'un-stick' its self coming out of Flugplatz on the first lap so no videos
When we got back I thought it best to get a few service things out of the way & I decided I would get it mapped after Christmas so ended up changing the following parts before then:
Plugs
Oil & Filter
Air filter
HPFP Cam follower
Timing belt kit
Water pump
Aux belt
Both front brake disc dust covers (one was bent and catching the bottom arm when going full lock)
None service things changed are:
New set of genuine floor mats
Shark Stage 1 Map
Black coolant bottle cap
Black washer bottle cap
MOT is due again at the end of March, I need some rear pads & discs before then and I'm going to change the rear dust covers too as they are flaking & look tatty. Annoyingly the PS3's haven't lasted long and I need another set for the MOT so I bought them a few weeks back. I grabbed a few photos of it today as we actually had a warm day!

I didn't get a before & after of the map at Shark, & to be honest I wasn't all that impressed so I took it to the RR again today to see what the graph looked like. This is what it made & the second graph is the before & after graphs overlayed.

I've booked up for the ring again in May so likely to be no updates before then. Hopefully I should be able to get some good videos this time around. Plans before the end of the summer this year are:
Revo intake
TT engine cover
Whiteline front & rear ARBS
Whiteline anti-lift kit
