Best thing you can add now if you're prepared to look at the data and get a little coaching is a Video Vbox........

There will be more time in you than there is in the car and it'll be a cheaper route to lower lap time. You've done the key bits to make the car faster, anything else now is going to find you tenths unless you add a shitload more power or Bosch M5 ABS.

VBox Lite or Vbox HD with an OLED Predictive lap time display are the way to go. If you want to come over I'm happy to lend you one to try before you buy.

Thanks Stephen! That’s incredibly kind - and I might take you up on it after a bit of coaching… I had a day’s tuition booked at Donington before the world went wrong, so I’ll get that rearranged first - I suspect as you say, that the main issue with the car at the moment is my skill level - and hopefully I can sort that out a bit soon :)

Holy Moly!!! That’s some dedication! :)

Totally agree with Stephen. You should most definitely have him install it then do a track day or two. You will enjoy using the software, it's user friendly and the predictive lap timer will definitely help on the day.

I already have the AIM dash, which does splits and lap timing - is this significantly different?

Also, already done radio and speaker delete, AC delete, engine bay trim delete, roof lining removal, Odyssey battery - but think there’s definite mileage in removing the carpets, passenger seat, bulkhead sound deadening and boot carpet for track days? :)

Thanks guys - I’ll give you an update on what I remove and how much it weighs! :)

AiM is awful, really great HD camera tho. Software and on track info is in a different league what Stephen is offering. Having said that I think the AIM V3 which my mate uses is better but not as good still.

CF seats and aluminium rails 10kg. Carpets and deading 5 kgs.

Lol remove passenger seat, that always makes me laugh, will it make all the difference on the day, NO :lolno: You'll need a passenger seat to properly learn.

Looking back, I wish I could have ragged my S2 like I rag my R300, it's all in the learning Matt.

Give or take depending on the driver even if you were able to remove 50kgs from the car this will equate to circa 0.4 - 0.6s per lap at Donington Park, a little more at Silverstone although it's not proportionate to the circuit length due to the undulation effect at Donington.

If a good instructor using a Vbox cannot find at least one second on a full days coaching from an amateur driver then they either aren't a good instructor or the amateur is already very good. i.e. coaching up to your own personal limit is typically cheaper than weight loss.

When we build Elise, Exige & 2-Eleven race cars we were using lightweight clams, 4kg bag tanks, fuel for qualifying would be weighed in, excess drained out via an MSA Approved fuel drain etc. In the 2-Elevens we had 'bag' seat when allowed that were 2kgs....... etc etc. That's all a bit excessive for track days and I wouldn't create a load of work for your self until you are at the point that you can get no more from yourself.

Then I shall resolve to try to restrain myself from messing further and just go have some fun! ;)

Cadwell Park yesterday! It was sunny one minute and then a bit of rain the next - so many red flags! :/ Managed to turn in a few respectable laps despite being on my 'wet' tyres... (AD08RS) Think I might swap them for some A052s very soon... Had great fun and Cadwell seemed to suit the gearbox much better than at Donny, but I guess that could be because I've not been to Cadwell very much compared to Donny, so my 'that's a 3rd gear corner' mentality isn't as strong at this circuit?

Definitely need to invest in some tuition as my next upgrade... :)

Yep I certainly think I'm struggling with that mentality. I was banging into the limiter like a nutter at Croft :lol: Saying that, I partly blame my shift lights, I've made some config changes on my dash to give me a bit more of a heads up.

I love Cadwell, mixed conditions there can be treacherous though.

I'd like to do a trackday on my AD08RS, I feel like in terms of learning the car they could do me a big favour - assuming the ZZR's have higher ultimate grip but a more sudden drop-off. I've never tracked a Lotus on anything other than ZZR, so my learning curve has probably missed a vital step. I'm with you on tuition too, I'm hoping to line something up this year and I'm also considering the Lotus Academy programme perhaps over winter to keep me distracted/skinted enough to avoid pulling the car apart again.
