Trackdays-A couple of issues
Discussion
Last night I took the beloved Chimaera 450 to Rockingham for a track evening,2 hours of open pit lane fun.
Exellent evening with only 30 peeps there and very well behaved they were too.
Got Through the Noise test 98db limit at 2/3 revs spot on 98 so all good there !
I did a 25 minute session rested for 30 mins then had 30 mins with an Instructor ,another 25 min rest and back out for a final 25 minutes.
After the 1st session I opened the bonnet to let the heat out and there was a trace of power steering fluid around the reservoir (more like a mist really,I released the cap and the fluid was boiling!
Guess I need a cooler of some kind then.
The other issue was tyres,Bridgestone RE002,s all round and they were brilliant for about 20 minutes then Huge slides were the order of the day,when back in the pits a close inspection revealed loads of graining on the tyres,I have the original 16" wheels spare so I am looking at track tyres ,Toyo 888's or similar
Does anyone have any recommendations?
The last issue-7mpg on Mr.Shells finest!!!

Power steering liquid is pretty normal considering 20 mins at full chat is actually a long time on track.
7 mpg,,, good man
It's pretty twisty at Rockingham so the tyres will be getting hot,
Yes 888's will be better but they will still overheat if provoked.
Sounds like you had a good time
Had a great time,Ive done over 30 track days at Rocky but all on bikes,1st time there in a car and I loved it (International sportscar circuit -Uses the banking in front of the pits but No chichane as its too hairy in cars!)7 mpg,,, good man

7mpg Butch,, could tell you ride bikes
If a Tvr is rattling around there I might pop over to watch next time.
7mpg,,, that's a bit high, must be running lean
I'll do Rocky one day as it looks a good test for both driver and machine, you obviously know the place well Butch, your cars steering fluid is just complaining,, I replaced mine for new and it still gets hot and as you say a slight mist/wetness appears around the bottle, I just rag it off and open the cap in between runs,, yeah and always open bonnet to let that heat out.
Slow gear changes and heavy brakes compared to a bike I bet, but such fun balancing g the car with its 50/50 weight transfer and lack of grip,, but oddly you can get em tucked in and turning well and getting pretty good G's all things considered.
I bet your buzzing
I normally feel on a par with Senna afterwards
It's a craic .
I was surprised that the lines were virtually identical ,The instructor pointed out that unlike the bike line on the righthand hairpin where you turn in late and get over to the inside of the track (the line I had been using which was resulting is massive slides and quite a bit of tyre smoke!!) If i turned in late but let the car run out to the outside curb I could apply more power sooner = Quicker laps.If a Tvr is rattling around there I might pop over to watch next time.

At the moment i am still on std brakes (haven't had time to fit the brembo's yet) but I can honestly say I didn't have any issues at all with them.
After 20 minutes with the instructor I was consistently using one gear higher a lot of the time.
I still couldn't catch the Pesky MX5 though!!

Did you ever do Cadwell park on the bike?
It's an awesome car track, in my opinion, and not as abrasive as Rockingham. Amnd whilst a right hand circuit, there are enough left handers to keep the tyre temps even, as well as enough bends and hills to keep you interested.
Here's what it looks like from another fast MX5
:
https://www.youtube.com/watch?v=xAZCOXpZCWY
On the tyre front, R888s, Yoko A048s or AD08s, Federal 595 RSRs, Dunlop DZ03s, Michelin Pilot Cups.
All pretty good, prices vary from under £300 a set to over £1000.
It's not about having racing slicks, it's about having fun, so your tyres need to do the job without necessarily being the best
My Absolute favourite although Assen comes pretty close.It's an awesome car track, in my opinion, and not as abrasive as Rockingham. Amnd whilst a right hand circuit, there are enough left handers to keep the tyre temps even, as well as enough bends and hills to keep you interested.

We used to hire cadwell for 3 days every year (Ducati Sporting club),raced there as well a real 'Mini Ring" if ever there was one.
Never done it in a car but that will soon change!

It's just great to hear of another Tvr being driven by the scruff of its neck.
Good on you Butch.
The Chap running the event said that without doubt it was the nicest car there and it was good to see an owner that wasn't precious with it (it is a very nice car though but life is far too short!)Good on you Butch.
