I'm only about a tenth faster so I'd say you were in the ball park 👍Finally had some time to get into the Street class cars, took me a bit to get used to the track (who was the knucklehead who decided on Autumn Ring Reverse?). But I did get down to 1:21.887, is that a good time? I know @praiano63 said he was a second faster but I can never reach his times, so curious if that is the typical range.
My biggest fear is that both of my cars need to be driven a certain way to be fast and not sure if my driving style will cause the car to be slow for the testers, but oh well.
Theres a lot of hills on certain turns that just upset the cars, the problem is that if you're not on the limit through those sections then you drop a lot of time. Certainly a challenge, if the car is stable then it is slow but there is a very thin line between fast and completely unstable
My car is stable and feels smooth on cornering, It just is slow.. So its as you have highlighted, I can't drive beyond a certain limit.. I may just make my car a little less stable, gain a second and then leave it in the hands of the testers. If I can drive it consistently and safely, others should be able to get a better time out of it.

Whoa! That looks AWESOME in that color 👍FITT Pro Touring GT

This is a tune which I think will be driven better by others than by myself. I can keep it on the track but I think it has better times in it than what I have been getting.
My backup didn't look too shabby either. I think you'd appreciate the colour of it. It was a hard choice of which to plump for in the end. Both cars were very good around Silverstone. The image below is my unused entry, looks quite mean I thinkWhoa! That looks AWESOME in that color 👍
Aston definitely has the looks out of the 2, but the Jag is not bad. Looking forward to taking it for a ride.
Looks fine to me, all parts and methods meet regulations as far as I can tell 👍@Bowtie-muscle Or @DolHaus
Could you just check over my tunes, make sure I've not missed anything or put a part on in error that is banned from each of my classes? I think they are within regulations but just need a double check. Many thanks
and maintain 60+mph on the last corner, this would translate at least mid 51s 
Nice, I approveMy backup didn't look too shabby either. I think you'd appreciate the colour of it. It was a hard choice of which to plump for in the end. Both cars were very good around Silverstone. The image below is my unused entry, looks quite mean I think
Looks intimidatingly fast, must be because I know it's yours.

My final FITT entry for this competition. Not the fastest horse out of the stable but one which can get good times in the right hands. Good luck with it testers
Perhaps this is wrong but, I did that while testing the GT's in the last challenge. Hit the outside was, barely with @xande1959 's, if anything it may have slowed the following lap which was the best even though it red lapped. Made sure it was clean, and then counted it. It would be very easy here to get "next lap invalidated", but I would say, if the tester IS SURE the following lap was clean, if it was the fastest it can count.@Bowtie-muscle - Quick testing question
Imagine the scenario:
Running wide or spinning on the last corner complex
Incurring "Next Lap Invalidated" penalty (no advantage gained in recovering from previous spin)
Set best lap on next Red lap (clean lap, no corner cutting that would result in new penalty)
Can we count that new best lap?

Notes :
This replica is based on a Courtenay Sport customer car, originally VX220 NA car modified with Z20LET engine transplant and Z20LEH K04 Turbo from Astra VXR offering better performance and reliability. The 450PP is limited in power to fit in the regulation FITT British Invasion Tuning Challenge.
The weight of the car is 875kg ( curb weight of NA VX220 ) with 45/55 weight distribution of NA car. Suspension has been upgraded with NITRON NTR Race Coilover 3 Way with ERS Springs at 500/550. The stiff springs and ratio are chosen based on well proven formula for track racer VX220 with sticky semi slick tires. The front springs are harder than usual this time, offering sharper steering with damper & ARB all around setup for balanced handling. Ride height has been lowered by about 2 inch from stock height, while the alignment is based on street / mild track duty range of values, and I used less rear toe in to give more play when at the track.
Transmission uses Turbo VX220 Getrag 5 Speed ratios and final. This offers much better spread for the added power and torque, giving nice pull without inherent wheelspin drama. Courtenay Sport also offer performance/track oriented Final Drive at 4.170, giving much quicker acceleration from 1st to 3rd gear at a cost of lower top speed.
LSD is based on OS Giken with custom job, torque preload set at 25% with 2 way setup, also 25% lock. This will give nice balance against suspension setup, while still giving good traction even on lower gear exit. Simply hammer the throttle when in doubt and let the rear kick a bit then the LSD will do it's job, just make sure to hold that steering wheel like a man.
The VX220 was tuned and tested at Brands Hatch Indy, Willow Springs, Tsukuba, Autumn Ring and Red Bull Ring. At Brands Hatch Indy, it managed 52.1s with ease on SH tire. I have provided a replay of the run for reference. A good run would yield 19s 1st sector
Sounds fair to me, the run between the line and the first corner is really short so its hard to carry any unintentional advantage that might be gained on the run up 👍Nice, I approve
Looks intimidatingly fast, must be because I know it's yours.

Anyone else have an Issue with that?
Two VX220s to go head to head
I believe it would be fair as long as the rest of the lap was clean, a 10 lap run could quickly become 15-20 otherwise.Sounds fair to me, the run between the line and the first corner is really short so its hard to carry any unintentional advantage that might be gained on the run up 👍
I just foresee having to do a bunch of extra laps to compensate for the 2 lap penalty
