Videos and Pictures from Oulton Park
Race 1 -
This video shows the first two laps where just missed Martin as he stalls on the line and make my way through from 5th to take the lead at turn 1 for lap 2. It then shows the penultimate, on which I set the fastest lap of the race, and final laps for the victory.
Race 2 -
4th to 1st in the first corner and then a simple run to the checkered flag.

Rear Suspension
Back from some time traveling in Australia to find out that John has been speaking to Brian at BDN Sportscars to source a replacement rear lower wishbone which is bent after the round at Oulton Park
I will add a photo shortly but the rear bar of the lower wishbone on the near side rear is very noticeably bent upwards. I must admit I did not notice it at the race but then I think it happened in the wet qualify and I did not push to the limit in either of the two races at a circuit I am no expert at. Could that be why I did not notice what must be a rear wheel with very little camber and some toe out instead of the norm toe in?
Could this off during the wet qualify session have caused the bent suspension?
The replacement wishbones have arrived and changing over is a reasonably short activity and we have plenty of time before the final round of the 2008 championship.

Oulton Park Double Header - Championship decider or will it go to Mallroy?
Quick summary from Oulton Park as I am traveling.
Turned up to the most rain I have seen all year, the paddock area was flooded and lots of reports of treacherous conditions during the Friday practice. Saturday morning dawned with the pause in the rain, although the surrounding area seemed to get rain all day.
The qualify session was wet although it was not actually raining and the car felt good although not very predictable at the rear. Well actually it was ok but the throttle sensitivity means its hard to invoke a slight slide in the wet or to control a slide to a small angle, it it either sideways or not which means its hard to feel the changes in grip level. All was going well until about half way through the session when I slided more under braking and turn in to Druids than I had expected and had a fun session of traveling on the grass and over the gravel trap. In fact I though it was ok once I held the slide over the grass but it was quite a wake up to realise I needed to accelerate, whilst off the track, to be able to clear the gravel and rejoin. From then onwards I did to push hard enough which mean I did not make use of the increased grip that was evident by the other improved times int he last couple of laps. This left me 5th in the first race (and behind Steve) and 4thin the second race. My worst qualify for over a year I think.
The first race went well for me, I just about missed Martin who stalled on the grid, got to 4th on the run down the cascades, 2nd after the straight and chased Steve for the rest of the lap. Steve was experiencing some brake issues and therefore lifted early for the entry to the first corner of lap 2, which I slipped past and pulled out a good lead. That is where it finished and although Oulton is a great track, it was a very quiet race for me.
The second race, at the end of the day, looked like it could be effected by the rain and therefore we decided to run the wet weather types to cope with any sudden down-poor. As it was the race was completely dry. I had a great start and drove around the outside of the 3 class C cars in 1st, 2nd and 3rd place which gave me the lead after the first corner. From there I took it easy and concentrated on the race win for the championship points.
So 2 race wins and fastest laps have given me 26 points from the weekend. Paul in class B and my closed rival for the overall Championship had a 2nd and 1st in a reduced points round and John in class C did not convert the weekend into 2 wins so the points are looking good.
Interesting results with brakes as well.
At silverstone, the newly supplied brake discs from Hispec failed after just 1 qualify session.
The much smaller spare for the rear, when fitted as a replacement at the front, lasted a full race.
The spare disc, supplied originally from Hispec to BDN Sportscars, ran for the qualify and 2 races at Oulton faultlessly.
Interesting dilemma for Hispec, original manufactured discs work fine, smaller spare by them worked fine, newly manufactures replacements (and there were 2 remember) both failed first time out! What to do then Hispec?

Silverstone: DONE, Oulton Park: BRING IT ON!
Silverstone Summary
As I mentioned in the rather brief summary of Silverstone, it was quite a successful day but also frustrating.
We went out in qualifying with the new discs, straight from HiSpec. I took it easy for the first couple of laps, let the brakes get hot and then cool and then put my foot down. Something like 7 of the laps in qualifying would have put me on pole in last years race and we were substantially under the lap record although I don't think I was driving brilliantly. Rather too many missed apex's and messy exits.
Once we came in from the session, we did a normal check over the car and were astounded to find the near side from discs to be cracked in two after just one session!. We checked the other side and found hairline cracks emanating from every mounting hole. Wow what Qualify Control.
We reverted the car back to running the original front disc on the near side and the spare from the rear (quite a bit smaller) on the off side, as per Donington and prep'd the car for the race.
In the race, I wanted to be nice and easy on the brakes so that firstly I did not overheat the small front discs and secondly did not have any issues with the potential imbalance of running two different specification of disc. My start was not amazing and I arrive into turn 1 with Steve ahead on my left and Doug beside me on the right. I held station, tentatively hit the brakes and slotted in behind Steve. Turn 2, both of us missed the apex. In my case I was trying to use engine braking up to the apex to save the brakes and this just helped the rear around a little more than I had expected. I was quite happy to sit behind Steve as I learnt new ways to drive the car with plenty of engine braking and to get a feel for the brakes but that was short lived when I had a good exit from the last corner on the start finish straight right at the time that Steve had a bad exit. By the time we reached the start / finish line we were side by side and I just slipped in front at the turn-in for the corner. From there I was able to steadily pull away without putting much strain on the car and ended the race with a decent margin. It was quite an interesting exercise and definitely concentrated your mind on carrying apex speed and maintaining pace even if you cant get the lines perfect due to a compromised entry to a corner. We even managed to get under the existing lap record, set by a Radical SR4 2 years ago, all be it considerably slower than we managed in the qualify session. I may have over done the gently gently approach!
Oulton Park
The car is now all ready for our next round at Oulton Park this coming Saturday.
At the Oulton Park trackday, we noticed a little liquid around the near side front but could not identify where it came from. Once the car had been sat in the garage for a couple of days it was obvious that the near side front brake caliper had a small leak. The internal seals had once again failed, good these HiSpec brakes! So last we fitted some new seals and made a few other alterations to the brakes to try to give them an easier time and minimise any potential issues with these.
The car is also in wet weather settings, ready for what is forecast to be a rather damp weekend.
As Hispec have been incapable to admitting there are a problem with the discs they supplied last time let along deliver any replacements, it was a fantastic to hear that Brian has found another spare pair of new front and rear discs that we can use this weekend.
As we lead up to the Oulton Park double header, here is a short in car lap of the Oulton circuit. I wonder if we will see if like this at the weekend or whether it will more closely resemble a pond!
