Today
@EthanMenace and I went to Anglesey for a track day. Anglesey had been on my bucket list as a track that I had wanted to do ever since I had seen photos of cars gong round the track with the coast in the background. The weather was a good 20 degrees centigrade and sun was hiding from time to time behind the clouds - it was perfect for a track day.
We decided to bring the Cup wheels with us as they still had some part worn Direzzas on them. Our plan was to try to look after the tyres by monitoring wear and tyres pressures rather than just shred them round the track. When we packed up the car for the trip to Anglesey we had looked at the Ultraleggera wheels which which had two very worn and laminated tyres - both tyres had taken some abuse on the front left side of the car. Neither of those tyres are really safe to use again.
The cars at the track day today were an odd mix of vehicles. There was some kind of Caterham meet going on as there were a lot of Caterham style cars and the drivers all knew each other. A local car club called the Flat 6 had turned up with a range of modern BMW M cars. There were a few MX 5s, a few Lotus Exiges, a Porsche 911. There were hardly any Clios. There was a 172, possibly two 182s. Apart from the Track Obsession red 197 were we the only other 197/200 there.
The track ran the Coastal lay out all day.
Since the last track day at Donington we had a few bits of kit to try out:
- Ferodo DS Uno front brake pads, Ferodo DS 1.11 rear brake pads;
- RaceBox Mini
- Some eBay special Go Pro camera extension poles
In order to improve the Clio in ways that does not involve increasing the power of the engine we had decided to invest in some brake pads that would have a bit more stopping power.
The RaceBox mini was a bit of an impulse purchase. It is essentially a super accurate GPS device that can ether be used in conjunction with it's own app, or a sensor part of Harry's Lap Timer. The RaceBox mini had been mounted on the cage using a GoPro camera mount with a threaded bolt. The RaceBox mini has to be mounted so that it is facing forwards and sits horizontal - unless you calibrate it another way. I was hoping that 25 hz device would be a bit more accurate than the 1 hz GPS sensor in my iPhone.
The eBay GoPro camera extension poles were simply to get better camera angles for the front and rear facing cameras. The front camera has a 15 cm pole that hangs down from the hoop of the cage so that the forward facing GoPro is now about eye level. The rear facing camera has a 25 cm pole to get the camera that is mounted on the rear of the cage closer to the boot lid.
After unpacking the car we set the tyre pressures trying to get to about 32 hot at the front and 28 hot at the rear. The Gaz Golds were set to 5 from stiff at the front and a similar setting at the back.
The first few sessions in the morning were busy as everyone was keen to get out on track. I used Harry's Lap Timer during the morning sessions but soon got frustrated when it started to count two laps as a single lap and skew all of the timings. The plan of using a super accurate GPS receiver with Harry's Lap Timer was not really working. The GoPros also decided to play up and while one would record the other decided not to record, and visa versa.
Despite those small frustrations the car felt really good and the track was superb. The stopping power of the DS Uno's was immense and allowed us to outbreak many cars. This put us in a position where we could make up time on the twisty technical sections of the circuit even if we cold not keep up with the more powerful cars on the straights. After flying through Church and on the approach to Rocket In cars were often breaking near to the kerbs on the left or the right. The DS Uno's allowed us to approach Rocket In at about 110 mph without breaking in the approach and then decelerate down to about 30 mph at Rocket In and not too much before.
As the morning progressed the tyres pressures were being kept at about 32 hot at the front and that really helped with wear on the front passenger side shoulder. We stiffened up the Gaz Golds to get a bit more rotation in to the rear, and to stop the car bunny hoping at School. I normally set slower lap times than
@EthanMenace but after a few sessions I had been fortunate with the traffic and had the best time.
I spent most of my day trying to perfect my entry and exit to Turn 1 and Church. They were both flat out fourth gear corners, but I always had to lift off the accelerator so that I controlled my entry speed otherwise I was going to come flying out the other side of the corner and spin out of control. Later in the afternoon when the rear dampers were set to full stiff the car moved around better and made these corners less scary.
Just before lunch we started to get a whirring noise coming from the passenger side rear wheel. The noise was more apparent when it was under a heavy load. After putting the rear passenger side wheel in the area it became clear that there was some lateral movement in the hub. The wheel nuts were torqued up correctly but the disc was moving very sightly. As we travel with a box full of tools were were able to tighten up the rear hub nut to 175nm and that seemed to solve the problem.
In the afternoon I stopped using Harry's Lap Timer and used the RaceBox app instead. This provided more accurate GPS information even though the same hardware had been used in Harry's Lap timer. The downside to using the RaceBox app is that I then did not get and telemetry data from the car such as the rev counter of throttle pressure. The app is okay and shows a reasonable amount of analysis.
@EthanMenace just got faster and faster in the afternoon compared to my times. I enjoyed some good sessions battling it out with other similarly powered cars like Civic EP3, and a Mini (albeit I have no idea what engine it was running). The Gripper made a big difference at Anglesey and it clearly gave me the advantage compared to some other cars. Despite not being as fast as
@EthanMenace I really enjoyed my sessions "racing" with other similar cars.
There were a few red flags today, but generally they were for cars breaking down rather than accidents. The most amusing red flag was caused by the chap who was using the garage next to us. His wheel literally fell off and bounced over the perimeter fence in to the sea. He was not injured and was more angry that he had lost a new tyre the he was about the wheel falling apart.
We carried on lapping until 5pm. We probably did about 120 laps at Anglesey so that means we did just short of 200 miles on track.
By keeping en eye on tyre pressure and wear we have managed not to destroy the front passenger tyre. The front left wheel was swapped for the passenger side rear wheel at lunchtime. The wear was more even across the contact area of the tyre. 31 Hot seems to be the current sweet spot for the front tyres.
Anglesey Circuit is quite literally on the coast and has some beautiful views that you can see from inside the car whilst you are going round in the car. The coastal layout is quite sympathetic to the Clio so it made for a really enjoyable day.
This is
@EthanMenace best lap from the afternoon.
When we finished at Anglesey we followed
@jimmybell recommendation and took the scenic route from Ffestininog to Bala along the A4212 and then took a route through the Snowdonia National Park to get to a hotel for the night to break up the long journey back to Essex.
The next track day is Snetterton on 4th August 2022. We picked up a used set of Yokohama AD08R last week and will probably get those put on to the Ultraleggeras. Out of the 8 worn Direzzas that we currently have we will probably make up a fairly worn set of 4 tyres and keep those on the Cup wheels. We will need a new set of tyres soon and I am eyeing up a set of MRFs which are now about £800 new for a set.
