The Pits 4,408 Posted January 2, 2015 Report Share Posted January 2, 2015 Most cars ground there with sufficient effort! It's the only thing that's prevented me from taking my car to Brands but as long as it's only the plastic chin spoiler it's no big deal. Must do the GP track this year at some point. Still my favourite UK track. Quote Link to post Share on other sites
DK7 11 Posted January 3, 2015 Report Share Posted January 3, 2015 @ Trevor What is your experience about Corsa vs. Trofeo? Street and Track? Thanks. Quote Link to post Share on other sites
Trevsked 766 Posted January 3, 2015 Report Share Posted January 3, 2015 DK7, I would put the Trofeos at around 5% or less better on track than the Corsa's however I have not tried both tyres on the same track unfortunately. With the standard geometry as set by the factory (I haven't had that independently checked) the car is fantastic on track with the Trofeos but in my view they do not feel at home on the road with the steering tugging at camber changes like it is running a little too much camber but this doesn't happene with the smoother Tarmac on track. In this respect the Corsas are so much better and the road drive both quieter and more relaxed/enjoyable but still the exciting car it has always been. It feels like the side walls on the Trofeos are softer perhaps and as I've said before I am concerned that the carcass of the Trofeo is not up to the rigours of British roads and puncture a little too easily. I have only tried the Corsa's at Silverstone and they were excellent in the wintry conditions of early December with the exception of the hairpin (don't think it's a 100% hairpin but it's close) where the front understeered a little, struggling for grip. I think the Trofeos may have been better at that point. Would I fit another set of Trofeos to my Cup? Not unless I spent far more time on track than the 4/5 track days I do a year. For thoses interested I paid £774.00 from memory for a full set of Corsas, Lotus spec of course and was quoted £2136.00 I think from Lotus for the same tyre. Trevor.

BillTheButcher 37 Posted January 3, 2015 Report Share Posted January 3, 2015 What's the tread depth on new Corsas? Quote Link to post Share on other sites
DK7 11 Posted January 3, 2015 Report Share Posted January 3, 2015 ca. ~ 6,5 mm 1 Quote Link to post Share on other sites
BillTheButcher 37 Posted January 3, 2015 Report Share Posted January 3, 2015 ca. ~ 6,5 mm Thanks. I asked because at the recent service they noted that it had 6mm left on all 4 tyres. Based on tyres I've bought for previous cars starting with about 8mm of tread, I thought there'd been a lot of wear for just over 1,000 miles. Quote Link to post Share on other sites
Jack 546 Posted January 3, 2015 Report Share Posted January 3, 2015 Interesting to see what is the geo of a cup or cupR. Lotus recommended geo specs for CupR: Camber: Front: -2.1; Rear: -2.25 degrees Toe: Front: .5mm out per side; Rear: 1.5mm toe-in per side 1 Quote Jack2008 2-Eleven2015 Exige V6 CupR Track videos ... http://www.youtube.com/jackcup2010 Lotus Challenge Series ULTRA Class champion2012 Lotus CUP USA OPEN Class champion Link to post Share on other sites

The Pits 4,408 Posted January 3, 2015 Report Share Posted January 3, 2015 Lotus recommended geo specs for CupR: Camber: Front: -2.1; Rear: -2.25 degrees Toe: Front: .5mm out per side; Rear: 1.5mm toe-in per side According to the supplementary manual the regular, road-legal V6 Cup is quite different. Front: Camber -0.4, Caster +2.8, toe out (per wheel) -0.03 Rear: Camber -1.9, toe in (per wheel) +0.3 that's for a load condition of two 75kg occupants and a full tank of fuel, tyres at 2.2bar front and 2.6 bar rear. CupR set up looks a lot more aggressive and no doubt shows a total disregard for tyre wear! Quote Link to post Share on other sites
DK7 11 Posted January 3, 2015 Report Share Posted January 3, 2015 So, the camper on the cup is very similiar to the standard v6. I've tought the camper on the cup is more. Has anybody the details of the standard V6? Quote Link to post Share on other sites
Freejack 113 Posted January 4, 2015 Report Share Posted January 4, 2015 Does anyone know the recommended tyre pressure for track use on a cup with Trofeos? Not the pressure for going road legal. I could imagine, that the way to decrease the typre pressure down to 2,2 on the rear could be the wrong way. Quote Link to post Share on other sites
Jack 546 Posted January 4, 2015 Report Share Posted January 4, 2015 I could imagine, that the way to decrease the typre pressure down to 2,2 on the rear could be the wrong way. Lotus recommends 32 and 38 HOT front and rear, respectively, for the CupR. I think the recommended rear HOT pressures are too high, but what do I know? Lotus handling gurus should be the experts here.

The Pits 4,408 Posted January 4, 2015 Report Share Posted January 4, 2015 I would say that sounds too high as well, those are the recommended pressures for road use. Legal reasons perhaps? Quote Link to post Share on other sites
LF1 564 Posted January 4, 2015 Report Share Posted January 4, 2015 We ran at the recommended road pressures above first time out - destroyed the rear tyres in a couple of track days. Quote Lotus Register - https://www.lotusregister.com Link to post Share on other sites
Trevsked 766 Posted January 4, 2015 Report Share Posted January 4, 2015 I believe it is 30psi all round (hot) and that's what I've been running without issue and have even tyre wear. I may try a little lower, maybe 28psi in the front next time out if it's a tight circuit. Trevor. 1 Quote I'll get around to it at some point. Link to post Share on other sites
Freejack 113 Posted January 4, 2015 Report Share Posted January 4, 2015 I went out for 30 and 32 (front/rear) with the already posted result. So I am quiet helpless. The front does not make any trouble, I am suffering with the rear tyres. Quote Link to post Share on other sites

Jonny, I believe 32/38 (f/r) is the cold pressure recommendation for street use, no?

Trevsked 766 Posted January 4, 2015 Report Share Posted January 4, 2015 That's my understanding although I thought 37 rear but not sure where I got that from. Trevor. Quote I'll get around to it at some point. Link to post Share on other sites

I've thought the PZero Asimmterico 2 (265/35/18) isnt longer available because on the Pirelli Homepage the size i'snt longer listed! See Link Quote Link to post Share on other sites
DK7 11 Posted January 7, 2015 Report Share Posted January 7, 2015 Pirelli told me the Corsa will be produced continue, but the Trofeo will be replaced by the Trofeo R in ~ April 2015. Quote Link to post Share on other sites
The Pits 4,408 Posted January 7, 2015 Report Share Posted January 7, 2015 Interesting. Pirelli claim the Trofeo R can last up to 80% longer and is already available in larger sizes. If some Exige owners claim to get through a pair of rears in a single track day, you can imagine how long they last on a big, fat porker! Hence, the Trofeo R. Quote Link to post Share on other sites
