Ummm..........You looked pretty fast in the 2-Eleven,so 14 seconds faster than that? Wow. You are moving, sir
Overall impressions on the Radical vs. the 2-Eleven other than it's a hell of a lot quicker?

Thanks for sharing

Well, the biggest differences in order of importance are:

1) Waaaaaaaay more aero downforce.
2) Paddle shift close-ratio sequential with flat upshift and auto-blip downshift
3) Dual master cylinder unassisted brakes with bias control and no ABS

The aero downforce is just incredible. At speeds below 80mph or so the handling is similar to the 2-Eleven, with a bit more grip. At higher speeds, the cornering and braking grip increases to unbelievable levels. It definitely will take some getting used to.

The close ratio sequential means you shift a lot more frequently, but the flappy paddles make it easy.

The brakes are awesome, but you have to judge optimal brake pressure with vehicle speed... when you have aero downforce, you can really hammer the brakes; but you have to quickly reduce pressure as the aero downforce bleeds off at lower speeds.

It's really quite well behaved at the limit... so far

Sounds awesome Andy. It must be a bit unnerving trying to figure out what the high speed cornering limits are. Sounds like it will be akin to an on/off switch (not so lol!). What influenced your choice in that line up?

Am I the only one that watched Andy's video of his new Radical SR3-RS? This thing is incredible AND it's British

Radical's are just on a whole other level, I've piloted many and Andy's synopsis of the car is spot on. You really do have to learn to "trust the down force", the cornering grip at speed with these cars is mind blowing.

Oh, and BTW Andy, congrats on the SR3 but sorry it will ruin you just about any other car.... :-)

I know it's late in the season, but checking to see if there are any track videos that have yet to be posted.

Seriously Andy, how do you trust that the thing isn't going to just fly off the track when you're taking a corner at 2g's? I've said it before, but that car, in the proper hands looks insanely fun.

BTW , is your steering wheel the size of a Cheerio? It's pretty darn small. Lol.
Thanks for sharing.

Dr. J, are you in the car with the camera, or in that white Exige? Wow, at the 1:50 mark that Exige was braking awfully late and went very hot into the corner. I watched it several times, laughing at how quickly he passed the two of you. He just couldn't match the power in the straights.
Thanks for sharing. I was thinking that track days were done for the season, but I hadn't considered that we have international representation on the forum.

Thanks...I was the one in the Exige...and yes, I'm brutal on brakes.

I lined up right behind the three Porsche 997 GTs in pit out...driving on a curent F1 track is just Lot(u)s of fun! I plan to do the Yas Marina track in Abu Dabi on March 14th.

The season for open track days in the Middle East is from the second week in September through the second week of May...the rest of the year is just too f-ing hot to do anything!

Dr. J,
What rotors are you using? One of my patients brought in a dba4000 rotor that he just purchased for his base 2.5 WRX. The rotor measured 11 1/2" in diameter and felt like it weighed 200lbs! I should have weighed it.
I just changed out the rotors and pads on my wife's mid size SUV and I thought the dba's felt heavier.

You don't trust that thing... at first. You gradually increase speed until you start to get the familiar sensations of increasing slip angle, understeer, oversteer, etc. Once you know what it can do, then it's a matter of hitting your marks (braking point, turn-in point, apex, etc).

lol, it's a pretty small steering wheel... and it's a fast rack (less than one turn lock to lock)... but the steering effort is not unreasonably high.

Nice rotors. I noticed at the 2:58 mark you get a bit squirrelly. Is that due to your having larger brakes up front and stock in the rear?

No...at that point I let the clutch out...Turn 1 is a 2nd gear turn and I'm still having problems getting it into 2nd gear. I've got the LETSLA and the Simply Sports Cars shift cables installed but I still need to adjust the whole shifting system. I think I need a larger plastic block (wider and longer) down by the shifter lever...there is one in there right now, but with the shortened throws of the LETSLA it does not do its job.

I do also think that my rear brakes are way under powered, but I'm still developing the car...I'll get there.

What do you mean "done for the season"? You mean some of you guys don't do this year 'round? Okay, so it's January and a bit chilly. And there's some snow by the side of the track. And occasionally somebody cuts a corner a bit and brings some of the white stuff onto the apex. Are you telling me you'd rather go skiing than spend a day at the track?

Not really a track video, but it is a Lotus Exige on a track...I’m in the Bahrain International Circuit promotional video for Open Track days… my car is at 1:06 – 1:07 and 1:16 – 1:17. http://www.youtube.com/watch?v=UBgd0fkm61I
