Oh yeah, i did go & it was great fun & super value.
So it was run as an "open pitlane" sprint, so there were no classes, silverware or running order.
It was just a case of it you wanted a run you got in the very short que for the start line. I think there were about 20 diffrent cars entered;
Toytota Starlet,
N/A MR2,
couple of Turbo Mr2s,
nissan 200sx,
Lexus 200,
Lexus 350,
Audi S4,
new Mondeo,
N/A Celica,
Celica GT4 (ST165)
mk1 mr2
Factory TRD Toyota Celica gen7 (newest shape)
Toytoa Aygo(not big power, but subtly moded to make it a track go-kart)
BMW 330i
It was a bit damp out & about & i had 3 or 4 runs & they were all around 64/65 seconds, i thoguht that was ok, but that there should be a bit more to come. A friend comes over & tells me i've been quickest of everyone so far, which was a nice suprise
Over the morning i had 8 timed runs, during the lunch break I had a long think about the logistics of getting back from Grantham to Kent to see the start of the Brazil Grand Prix. I reckoned if i left the sprint early i should be able to get back in 2 & 1/2 hours, so deicded that i would have a few runs after lunch then pack up & go home so i could (hopefully) see it.
Straight after lunch the constant drizzle slowed up a bit & i set off on a run it felt fast & tidy, but equally quite on the limit, i came through the finish, glanced up at the caravan & i had done a 62.74 knocking over 1.5 seconds off my best time that day

I got straight back in the queue went out again & over drove a bit. Went out again & outbreaked myself at one of the chichanes & just about avoided collecting anything. Went back out, again was still trying too hard.
So as i'd then had 12 timed runs & seemed to be chasing my own time i couldn't catch i decided to pack up & try to get back for the GP.
I set off with satnav saying journey time 2:45 & the race was due to start in 2:20

sadly the traffic conspired against me & I was on the QE2 bridge as the race was due to start & i was resigned to the fact that i was going to miss the start & first 15 mins. Then as i'm at the tolls they announce that they are delaying the start due to rain as they cleared the grid.....

Could I really make it 2 juction round the 25 & then another 7 or 8 miles home????Well i did, granted it required a spirited drive, but I ran through the front door they were on the formation lap. 8)
Top 3 all day were:
Adrian Smith TRD Celica 67.11
BMW 330i 66.63
Me in the GT4 62.74
A really fun day & i can't speak highly enough of Javelin Trackdays having been to half a dozen or so sprints they have run, plus the value is superb for sprinting. Thankyou very much Dave (Prolex-uk) for getting me involved.
