Emira track impressions

I have quite a lot of experience driving at the track, and since my Emira is now broken in and has some fresh brake fluid from the dealer, I decided to take it to Laguna Seca.

My car is the V6 with 6MT and the touring suspension and tires (Goodyear Eagle F1 SuperCar 3).

Having heard that the stock pads don't hold up well, I put in a set of EBC SR11's.

First off, the tires stink. They can't handle the heat on a cool December day. I get maybe 6 laps before grip falls off noticeably and they get greasy. Also, the SR11's completely overpower the tire grip, even before overheating.

You also need to run high temperature fluid. My fresh fluid resulted in a soft pedal, but the brakes worked. The calipers got hot enough that I melted off all my little rubber bleeder nipple covers, and they went from being a bright red to a dull brown.

The car itself is nicely balanced. I found that I could manage under/oversteer just like in a big, fat Elise. You definitely feel the weight of it in the tight turns, but it's remarkably capable coming out of a turn. The Elise has this "hooked" feeling throughout a turn, the Emira is kinda unsettled going in, but once you get on throttle coming out, it feels great. You have to drive it differently, since you have more power and more weight; braking happens earlier, turnin happens earlier due to bigger slip angle, and the difference in engine torque means you need to manage the throttle more, no pinning it to the floorboard.

The heavier car, power steering, and huge wide tires means you can't feel what it's doing as well, but the absolute grip is pretty nice. Due to the lack of feedback, it's easy to overdrive the car.

So, I enjoyed the hell out of it. My laptimes (1:45 ish) aren't bad for a completely stock car on street tires. I get my Elise down to 1:41 on street tires and 1:38 on slicks, but that car's got a proper alignment, great tires, Nitrons. There's lots of potential here, but I'm going to have to do some work.

In track mode, when the weather got cooler, I exceeded the Laguna sound limit. When it was warmer mid-day, the car stayed below 92dB, but once a cold front came in, I blew a 94.9 which sends you packing home.

Interesting note: Track MPG = 3.9, based on miles on odometer divided by miles. The computer said 4.2 mpg. It's hilarious to see 50 miles range remaining on a full tank.

So, before I track it next, at minimum, I'll do the following:
  • Castrol SRF
  • More camber
  • Proper tires
  • Better bleeder nipple covers

Longer term:
  • Suspension, the touring one doesn't cut it.
  • Some kind of seats + harnesses, so I don't flop around.


I'd post video, but my stupid Smartycam recorded all the times I was parked in the paddock and turned off for the laps. Go figure.

Great write up and feedback! I'm surprised you didn't order sport suspension if you intended on tracking. I was reading where the sport was very compliant and rode nicely.
I'm curious with the sound level being crossed are you running all three cats?
Keep us informed on your upgrades and how well they work.

I bought one of the many orphaned cars that were sitting on dealer lots that someone else gave up waiting for. This one had everything I wanted except the sport suspension.

I love the color. It came down to sport suspension on a dark verdant car or touring on this one, so I bought the yellow since it’s easier to change a suspension than a color

Assuming the Emira isn’t too far off the performance of the Evora GT, you shouldn’t have to do anything to the car to put laps down sub-1:40 unless the tires actually are that bad or the suspension is just too soft. If you intend on tracking that car I would suggest continuing to take it out as-is until you’re more familiar.

Oh, the tires really don't hold up, they were terrible. I'm sure I could do a lot better with good ones. I want to go down to 19" wheels with Bridgestone RE71RS. What I learned from 16 years of tracking my Elise is that you only change one thing at a time. In this case, I'll deal with tires and alignment first. I scrubbed the outside of the tires quite a lot and barely touched the inside.

After the first couple of sessions, my laptimes got super consistent and I felt like I was pushing the car quite close to its limit. I did have a couple of worse laps but those were caused by my mis-shifting because I have a hard time heel-toeing this car. It's really odd - the SR11 pads are just way too powerful for the tires, and I could never depress the brake fully when the fluid was cool, and then the pedal went too deep when the fluid got too hot. There is a LOT of heat going into the calipers, as I said, mine changed color and the bleeder dust caps melted off. I'll put in street pads today, and I'm curious if the piston dust seals are gone too.

Yep. Except for brake pads, my car is as it came from the dealer. Laguna is very finicky, and sound carries better when it's cool and when it's cloudy. Ideal day for noise is sunny and warm, worst day is cold and foggy. I was running in track mode all day and measured under 92 (the limit), and then the temperature dropped about 10 degrees when a cold front came in, and that was enough to change the readings. Everybody was getting dinged for sound. They are ruthless about it now.

Ferrodo DS2500,the stock pad I believe would be much better with stock tires. Get on Blackwatch to get us the adjustable front control arms. Single best upgrade on my Evora I just sold. I bet car will be very happy with wider track at -3 degrees, 0 toe , maxed caster up front and all you can get rear, cutting toe in half.

Laguna Seca is a counterclockwise track that works the tires on the right harder. This is the front right. This tire has 1200 miles on it, about 80 at Laguna Seca :) Those center tread blocks are worn off at quite an angle. My pressures got too high, and I definitely overdrove the tires, so chalk that up to driver error.

I was running stock pressure hot, so 29F 32R. It was a glorious day and I put lots of heat into the tires, so cold pressures were like 7-8 PSI lower.

The pads got super hot, and changed color through about half their depth:

And here's a comparison of deceleration coming into T10 as an example, between the Emira with the SR11 pads and Elise with XP12's. The Emira initial bite is far harder, and then the deceleration lets up as the car starts to slide. I'm going to run milder pads next time.

I don't know, honestly, and the rotors are 2-piece, just not separable, but that should not matter because the heat is generated between the pads and the rotor, no matter how many pieces it is.

Strangely, the paint mostly recovered over night, the calipers are now a slightly darker red, but not brownish. Go figure. I've never seen that happen before.

I also find it very odd that I lost all my bleeder valve dust caps. I saw some white residue where they used to be, but maybe they just deformed and popped off.

You kidding? You haven't properly bedded a set of Pagid RSL29s till they are smoking and the Yellow paint is cooked.....
 
#18 ·
Same concept. paint burns off. If surface of pads are scoured, then they overheated. By Scoured, material surface very irregular. That's all. Glad to see you confirm my thoughts. Touring makes a beautiful street car but with skills it will be overwhelmed on track. I assume the car you found was an FE1 priced car. You paid what they are worth.
In 13yrs of Evora track work, I never overheated ATE Type 200 fluid, and I was ruthless on the brakes when I wanted to close a gap on big HP.

  • Castrol SRF
  • ...
Not for nothing, but with all your track experience one would have thought that this is the first thing that you would do along with swapping out the brake pads...

Thanks for a great write up regardless. It is a bit bothersome that those rubber bleeder caps would melt off and the calipers change color. Can you post pics of the caliper?

I'm waiting on some confirmation that 19" wheels fit, and once I know for sure, I'm ordering a set and putting Bridgestone RE71RS on it - which I love. On my Elise, they're incredible. We'll see how a heavy monster like the Emira does on them. There's little info available on good track setups for this car so far, so I'm going to have to experiment a bit.

My next trackday will hopefully have the following:
  • Bridgestone RE71RS on 19"
  • A bit more camber
  • Castrol SRF
  • Less aggressive pads (EBC SR11 had way too much bite, it was difficult to modulate).

Also, it's a bummer it doesn't pass sound at Laguna Seca. I'll need to try an exhaust valve controller or fab some laguna pipes.

It turns out that 19" wheels don't have good tires available, so the two options are to go down to 18" and lose the rear parking brake (which I'm unwilling to do) or buy 20" performance tires. I decided to go with the 20" option and picked up a set of GRP wheels. I'll be trying out Dunlop Sport Maxx Race 2 tires first, and if I don't like those too much, some form of Michelin Cup tires, and if I care to tow the car to the track, there are also Hoosiers available in 20" sizes.
