Sodegaura Forest Visit 2.

Visited Sodegaura Forest raceway against this Sunday. Fantastic weather. Am really loving this track. In particular corners 3 and 4 are wonderful. Forth lap of the day I actually took 2 seconds off my previous time and ended up with a 1'21.72. After that I had some trouble with air in my brakes and I never could improve on the time as I lost some of the control over the braking - particularly on the inside of the course. Later when I bled the brakes I found some air in the front right. I guess I didn't do a proper job bleeding them the last time or something. Hopefully, I'll have no further brake issues next time out.
I'm still lost as a little puppy on corners 5 through 8 but am starting to get a rhythm elsewhere. It definitely felt a lot more familiar on my second visit though. I can only look forward to my 3rd.
Sodegaura is quite kind to the brake pads I've noticed. It's also quite kind to tires as there is a good mix of left and right handers. Hmmm. Perhaps that is why I'm so lost on the inside of the circuit. I probably do left hand corners a lot more naturally than right handers. They are hard/long corners though
No camera yet. Still have to sort that out. Perhaps santa will come?
My Fuji Speedway license expires on the 15th of this month. I'm thinking I'll let it run out at this stage and skip it for a year or so. I didn't go there at all last year so it was a bit of a waste.
Anyway - looking forward to my next day out again. No plans just yet.

Brake Overhaul

Decided that my brakes were long due an overhaul and decided that rather than hand it over to a shop to do it, I should take on the challenge myself. I just did the front brakes but I learned loads doing it. I'm going to do the rears another day. Hardest part was getting the piston out without an air compressor. That worked out to be a trip to the local gas station for each caliper. Most worrying thing was the continued leakage of fluid out of the open lines while I was doing it. I need to find a way to seal the lines for the next time I think. It would have made the thing a hell of a lot easier as I had to keep an eye on my master cylinder to ensure it didn't run dry. The kit cost about 6000 yen from Mazda for front and rears. Well worth it! Nice firm brakes again.

Sodegaura Forest Raceway.

I took the circuit license at Sodegaura Forest Raceway with some of my mates about 2 weeks ago. Fantastic day. I did two sessions. First session I drove well within the car as I drove around and tried to learn the lines etc. I think I got a 1'26.9 or something. 2nd session I drove faster each lap and ended up with a 1'23.7 but there is still loads more time there. The circuit is very interesting and has some fantastic corners.
Corner 1 is a rather brave corner. You come at it quite fast after a decent straight in 4th, brake and I think take it in 3rd. It's blind and always seems faster than you think but you don't really want to run out of space on the exit either. A good exit is very important though as the next part is uphill and its quite a while before you get on the brakes again.

Corner 2 is flat out. It's always a rush keeping full power down, nailing the apex and floating out towards the edge of the track on exit... Easy to turn it too early and muck it up as its blindish on the way up to it.

Corner 3 I'm unsure. It's super wide on the exit of corner 3 but corner 4 follows soon after and that's the next important one. I downshifted to 3rd but kept reapplied power on the way into and out of it. It seems fast enough and stabilizes the car for braking into 4.

Corner 4 is fantastic. At first it seems like a slow right hand hairpin and its easy to take it like one, but infact the exit is as wide as the entrance and its important not to slow too much and maintain momentum. I brake early way out, rotate the car early and I'm way on the power before the apex. It was really fun to feel the car rotate all the way through that corner as you balance braking, turning and power.

Corners 5, 6 & 7. My word. It's downhill into these. You can't see the apex at all as its way below you. Plus the corner itself is a combo all in one direction. It goes on forever! I found it impossible to take it anywhere near right. I noticed cars not really braking too much for it but my brakes started to go off mid my last session and I'd no precision left in them. This corner will be one of the challenges for the next time. Love it.

Corner 8 was another tough one. Very wide with a million lines around it. I noticed a lot of cars going in very early into this one and understeering all the way around it almost. I opted for going in deep, braking hard but short, early rotation and power down all the way, way before the apex. I think a mid line might be better though - going in and not braking as hard, rotating on throttle and then powering out.

Corner 9 was pretty easy. Just a hairpin which I can pretty much do easily enough since I've done so many laps of Tsukuba :-)

Corner 10 is quite crazy. The entrance is blind, there is a concrete pit wall on the right and not much run off on the left. It's right before a long straight so its vital to be quick through here for a good lap time also. I'm slowly working my way up on that one also. There is also a highish rumble strip on the inside of it which I haven't quite figured out if mounting is a good thing or not. Not a good place to have any kind of action in the car except a nice clean fast exit. Thrilling though :-)

I must figure out what to do about my video equipment as it's ruined :-( I think I might get a helmet mounted HD cam or something next and see how that works out. Going to go one more time in December.

I've another race this weekend at Ebisu circuit in the Prelude. Looking forward to that although it snowed there today so hopefully we will be able to race. We were 3rd in class the last race but we couldn't drive the last 1.5 hours as it was fogged out.

Lack of updates => lack of racing!

Well, it's been forever since my last update. I still intend to getting around to uploading the race video of the last race. Not sure why I just can't get around to it. Footage is downstairs on another machine so perhaps its just laziness.

In the mean time though, you must be wondering why there is no updates. Well. I missed the next race as I was out of the country and then the last race of the year, they changed the regulations to the new ENDLESS brake pads. As the pads change the behaviour of the car quite a lot, I missed the next race as I had no time to go out and practice. A new year brought new hope, but 2011 was a hard year in Japan and thus another year slipped by it seems. I haven't been to a circuit this year in my car yet.

The last typhoon that hit Tokyo also saw disaster hit as my roadster let in some water which pooled behind my passenger seat. Unfortunately, my TraqMate unit and Chasecam unit got fried as they were connected into the car battery and sitting in that little pool. Not pretty. So my camera functionality is gone now in the car. I guess I need to invest again :-(

I did one race in the Prelude this year though in August. It was the 12 hour endurance race with TGR. This ended badly too though as we suffered a failed drive shaft 2 hours into the race and I never got my time behind the wheel. What a year - huh!

And now for some good news... After many years of wanting one, I finally decided to break down and buy myself a new racing suit. My old AlpineStars suit was becoming too old and it tends to cook me alive in the summer. To replace it, I bought a Stand21 suit which I had built to custom measurements. This is fantastic as it fits like a glove now. Along with the suit, I got some new nomex underwear and gloves so I'll be a new man next time out.

Next time out is actually this weekend but not in Tweety. We're back at Ebisu circuit again but this time for a 6 hour race. Really looking forward to that. I am planning to get a circuit license for Sodegaura Circuit in November. I still have my Fuji license but I didn't get to run Fuji at all this year.

That's all for now. Hopefully more good news follows after our next race.
