Edmonstone did it but I went via CMC. They were who Craig trusted to make the changes as my setup is now quite different to stock. Not cheap but they did a good job.Stu160 wrote:Hi Saj

That's unfortunate but I've read that about quite a few different tyres in the past - must have got a dodgy tyre. Would like to try ZZR but they don't do them in Evora 20/19 sizes.Andy G wrote:Baz had a cup 2 fail on the last trip.
ZZRs fitted and the race guys swear by them.

Re: V6 Tyres
Mik,
Kenny Broon is excellent. Lowered our MX5 by 25mm with Eibach springs then set geo for fast road, transformed the car from a moderately quick roadster to an almost on rails Lotus .

Re: V6 Tyres
Here is something posted by Blinky over on Seloc about tyres on the V6:
Have used just about everything (not slicks) on a V6 so I’ll share what I think……..
Starting with the common.
V6 tyre choices:
Avon ZZRs 215/40R17 265/35R18
Advantages:
"easier" to drive with less understeer. Note 215 fronts.
The compound gets harder and harder with more age/heat cycles, eventually gets hard to the point where they stop doing much work and becomes ever lasting, turns to wood.
Stiff enough to hold high loading on track and can run low pressures.
High (relatively) dry slip angle.
Disadvantages:
Not amazing ride comfort to begin with, crap ride comfort once aged.
Okay-ish in wet when new, average once aged, questionable in very wet and very high speed conditions, wouldn’t want to do 140+ in the wet much. A bit like R888s, funny that?
Can only order from Avon Motorsport.
Subjectively, allows novices to get away with bad habits.
Subjective dry track sticky rating: 7.5/10
Subjective wet track sticky rating: 5/10
Pirelli Pzero Corsa 205/45R17 265/35R18
Advantages:
Reasonably comfortable for road use.
Easily available off the shelf, doesn’t need to be a Lotus stamped tyre, common standard road tyre.
Middle of the park performance everywhere, dry or wet, similar lateral (sideways) and longitudinal (forward and back), no surprises, won’t upset new users.
Similar behaviour in the wet, won’t overly upset new users
.
Better wet braking than the Michelins.
Probably the safest all-weather track tyres…
Disadvantages:
Not as comfortable as the Michelins, see below.
Melts at high temp.
Disintegrates at high temp.
Goes off quickly with heat cycles.
Standard road going structural stiffness, can’t keep its shape with high loading or low(er) pressures.
Boring.
Subjective hot dry track sticky rating: 4/10
Subjective wet track sticky rating: 6/10
Pirelli Trofeo R 205/45R17 265/35R18
Advantages:
Probably the stickiest road legal compound available for the car.
Stiff sidewall, can run whatever pressure you like.
SeriouslyLotus / Demon Tweeks has them in stock or available in a few days.
Some OLD Official Lotus Dealer sometimes have a few in case of emergency. (Or pull them off a car in the forecourt).
Compound is sticky even at road temp.
Progressive break away in the dry, reasonable break away in the wet.
Reasonable mildly moist traction provided there is temp in the compound.
High (relatively) angle.
Doesn’t mind high temps.
Long endurance.
Disadvantages:
Takes a “little bit” of time/temp to extract full potential from sticker fresh.
Crap ride due to stiff sidewall. Your girlfriend looks at you funny.
Even worst ride when old and getting thin.
Pothole events becomes alarming.
Expensive initial purchase. (That may last a while provided they are cared for)
Retains the full understeery handling characteristics of the Exige.
The higher performance can relatively easily allow the user of an Exige to go beyond its design parameter. (Engine Mount / suspension(runs out of bump))
High hot grip allows novices to ride some amount of understeer around without overly noticeably appearing to be slower than Clios.
High speed and or loaded car + deep standing water = red flag/black flag or both.
Due to initial tread depth, the police sometimes like to chat with you.
Subjective hot dry track sticky rating: 9/10
Subjective wet track sticky rating: 7/10 (provided you’re not putting it through a lake.)
Khumo V700/V70a 215/40R17 265/35R18
Like a Trofeo R, but slight worst in every single way except cures a bit of understeer.
Yokohama AD08R 205/45R17 265/35R18
Advantages:
(Initially) More comfort than Trofeos, WAY more comfortable than ZZRs on road.
Cheaper than Trofeos.
Doesn’t mind high track temp.
Good road performance.
While not a proper race tyre, good track performance.
Clears a surprising amount of water.
Stiff sidewalls.
Lots of initial tread.
Like the ZZR, as the compound age with time and heat cycles, the tyre goes solid and thus lasts forever and ever.
Has a cool looking tread pattern.
Exactly what you want if you have just begun doing more than a few trackdays but can’t justify a Trofeo yet. i.e. a tyre that lasts a long time with track use but won't take away those lesson learning oppotunities.
Reasonable slip angle.
Disadvantages:
Not as sticky as a Trofeo despite suffering a stiff ride especially when old.
If there are no stock in Exige rear sizes available in the UK, it could mean waiting a month for the ship to arrive.
As the compound age, ride comfort disappears, dry performance levels off to that of a standard tyre, wet performance becomes questionable, cold weather performance isn’t there, generally the performance falls of a cliff after a year of normal use.
Initial circumference larger than other tyres of the same size, need to mentally recalibrate car speedo vs GPS speed.
Like the standard relationship, it’s everything you want when new, but slowly becomes an emotional death sentence after 12 months, except there is still tread left, so financially you don’t want to bin it yet, similar to a bad marriage.
Subjective hot dry track sticky rating: 7-ish/10
Subjective wet track sticky rating: 7.5/10
Michelin Pilot Sport 3 205/45R17 265/35R18
Advantages:
Off the shelf availability.
Soft construction, very high road comfort, comfortable enough to make an Exige feel actually comfortable, even if you live in Manchester.
High initial grip at road temps.
High wet performance.
Higher wet lateral grip than Pirelli Corsas.
Clears more water than Corsas.
Longer life than Pirelli Corsas unless abused beyond intended purpose.
Reasonable dry road performance.
High-ish slip angle.
Disadvantages:
Not easily available in Exige sizes.
Quickly melts on dry track.
Weak sidewalls made for comfort.
Poorer wet braking performance than Corsas.
Minutely worst dry performance on track than Corsas with higher slip angles.
Muted feedback.
Subjective hot dry track sticky rating: 4/10
Subjective wet track sticky rating: 7/10
Probably the best tyre for pure road going Exige pilots…
Michelin Pilot Super Sport 205/45R17 265/35R18
Like a Pilot sport 3, but slightly sportier, slightly worst in the VERY wet.
Still melts at high temp, less muted feedback than PS3
Subjective hot dry track sticky rating: 5/10
Subjective wet track sticky rating: 6.5/10
Probably the best tyre for the average Exige pilot who does 1 slow trackday for 10 laps per year.
Michelin Pilot Cup 2 205/45R17 265/35R18
Advantages:
High dry grip performance, in a comfortable package.
Retains the soft sidewall for road going comfort, relaxing ride home from circuit.
High dry track performance, not like a Trofeo R, but can momentarily be loaded up before levelling off.
Very predictable on dry track, predictable high angle break away in wet.
Deals with standing water better than some other track tires.
High temp survivability, doesn’t immediately melt.
Predictable wet performance.
Long life on road.
Disadvantages:
Poor availability.
Expensive.
Soft sidewall means no track running with overly low pressures, 29psi is about the limit before the tyre really says NO!
Less feedback than other track tires.
Less ultimate grip than a hot Trofeo.
When hot, can pick up an alarming amount of discarded rubber during cooling down lap, not dissimilar to previous F1 end of race weight management tactics. Once attached to the tyre, if not removed immediately, can chemically bond to existing compound ruining the performance of each tyre permanently. Not impossible to leave a circuit with more tread than arrived.
6 “sensible” trackdays with a “sensible” number of sessions of “sensible” durations will end a set, by tread depth and by heat cycles. 2 FULL! days at Spa going all out will end a set.
Will melt very quickly on a HOT summer trackday if pushed for long durations, and also permanently cook the compound.
Due to higher ultimate hot track grip and soft construction, additional adjustment to compression and rebound needed to compensate for very fast track use, perfectly fine for regular road or track use.
Subjective hot dry track sticky rating: 7.5/10
Subjective wet track sticky rating: 5.5/10
Perfect for a long distance multiple day European trackday trip.
Continental TS850/TS830 205/45R17 265/35R18
Advantages:
They also come in normal 205/45R17 265/35R18 sizes.
Don’t get stuck when it snows.
Full performance from low temperature.
Good performance when cold/wet/icy.
Soft and comfortable.
Easily drive up snow covered hills while pointing finger and laughing at Range Rover/Discovery/Qashqai/Juke/CRV/X5/X3/X1/Q3/Q5/Q7 captains.
Look like driving god on moisture saturated trackdays. (until they see what tyres you're on)
Not as bad on a dry track as a landsail.
Disadvantages:
It’s a set of tyres you won’t be using for the other 6 months.
Doesn’t like high temps. At all.
What idiot drives an Exige in the snow. (Me, to get to a snow covered trackday)
You can’t outbrake an Aston Martin Vantage GT4 on slicks in the dry going into McLeans.
But if you do, he will look funny at you.
MSV staff will laugh at you.
High slip angle means you have to slide everywhere on track, wet OR dry.
Everyone in the pit lane laughs at you, momentarily.
Subjective hot dry track sticky rating: 3/10
Subjective (heavily) wet track sticky rating: 9/10
Hope that helps.
