Who here has tracked their Emira?

[Blackthought_]

Anyone here track their Emira? If so, did you track the car 100% stock or did you upgrade parts? Particularly interested if you changed out the brake fluid, pads, tires, etc.

Would like to hear about your track experience with after market rotors for track. I have used AP J-Hooks (front) and DBA (rear) for years on my GTR's, but not available for Emira. I have used other brands that didn't work well, and hopefully there will be some of you gain the experience of which rotor to go with for the Emira.

Usually GiroDisc puts out left/right specific rotors for front and back, but they don't appear to b out yet. Typically, Inokinetic sells them once they are available. Hopefully GiroDisc or AP put out options soon.

I ran track mode. Never had an issue, car stepped out once or twice but I wasn't looking at the dash to see how many lights came on. There's still a full disable button for ESC and Traction even beyond putting into Track.

There is?

There is?

Yes, if you look at the center screen, there's an option to completely turn off ESC under track mode.

 

[F1 SML8R]

The only thing you can't turn off is ABS. I think it's a DOT/Uncle Sam thing at least in the states.

 

[GRP]

We have front and rear slotted rotor options in the works currently, they should be ready to roll around the end of the month/early May hopefully.
Fronts are just being restocked, rears are new to fit the Emira.

Great to hear @GRP Honestly, I was a little surprised the usual suspects hadn't put out a product yet.

I have the Rotora from GRP. They do not work with EBC Bluestuff pads. I ripped serious grooves on the rotors after a few track days. Needed to have them resurfaced. I'm trying them now with harder pads. That seems better after one tough track day.

Girodisc rotors on my NSX have been the best I have ever used with their recommended track pads. Waiting for them to make them.

What have you experienced differently with it off completely? I’m worried about oversteering

Being totally unaware of all of this, a follow up Q
What does Track do to ESC, that is therefore different to Sport mode? Its obviously still active in Track, or there would not be an additional button to turn it off completely.

This is what's referenced in the Drive Modes Explained thread:

Thread 'Drive Modes explained and Lotus Dynamic Performance Management'

Oct 10, 2021

A few questions have come up about traction control, sport mode versus sports suspension and what the Track mode in the Drivers Pack does. Here's an overview and links to more details.

First, to clear up one area of confusion. The Emira has two suspension options, Touring and Sports. There are also two (of four) Drive modes called Touring and Sport. Although confusingly these use the same naming, suspension and driving mode are completely separate. The suspension is passive and switching the driving mode doesn't change anything about the suspension.

2. SPORT

• Engine maximum rev limit: +200rpm
• Throttle progression: increased
• Exhaust valve behaviour at idle and when driving: open at idle (yay!), opens from low throttle load/rpm and is fully open above 3000rpm
• Launch control (auto and DCT only): available
• DPM characteristics: Understeer Recognition reduced, increased Slip Threshold and increased yaw angle available

3. TRACK (for cars with Drivers Pack, including First Edition)

• Engine maximum rev limit: +200rpm
• Throttle progression: optimum
• Exhaust valve behaviour at idle and when driving: open at idle +200rpm, opens from low throttle load/rpm and is fully open above 3000rpm
• Launch control (auto and DCT only): available
• DPM characteristics: Understeer Recognition off, ESP intervention level increased to high, traction control system calculates available grip and optimises torque to maintain grip and minimise understeer

4. OFF

• Engine maximum rev limit: +200rpm
• Throttle progression: optimum
• Exhaust valve behaviour at idle and when driving: open at idle +200rpm, opens from low throttle load/rpm and is fully open above 3000rpm
• Launch control (auto and DCT only): available
• DPM characteristics: traction control and ESP completely switched off

My left rear pad wore out more than my right rear.

I've been going faster at the track. I've been running sport mode. I'm more comfortable after reading more about it. I think the car is doing way to much.

The first set of OEM pads lasted 8 or so track days. Then the aftermarket ceramic pads (not track pads) only lasted two days. But a far more bumpy track (Sebring). Then I'm going faster each time. I'm pretty sure the last 5% of braking does a 5x wear and tear on pads and rotors. I'll know more after this weekend.

8 track days?! Wow. I haven't looked at my pads yet, but I know a couple different people who went through pads in 1 track day. I suspect I'm 3/4's in at this point.

Rears went that long.

I went through 1/3 of my semi-metalic race pads on the front in one day.

Was Mike your instructor at Sebring?

Accurate. The thinner the pad gets the more heat transfer goes through the pads and into the calipers. This is how you melt caliper seals and warp rotors.

Most clubs have in their tech inspection sheet, min 7mm of pad to start a track day as you're likely to burn through the remaining material quickly (normal starting is 17mm-ish to 25mm in an enduro type setup).

Also, I'm one of the people that went through the OEM pads in a single day at Laguna Seca. It is a hard on brakes track. Would recommend when you swap to move to PFC (preferred), Pagid, or Hawk as a pad that can actually survive the track if you're going to keep going.

For the first day, yes. Then I had Ethan for the afternoon last Sunday.

So the Rotora H8 pads pushed hard did about the same as OEM pads taking a bit off. I pushed the H8s all day. The day I was stuff with OEM, I worked into it. I think its the hot time that really trash the pads. I'm going to run the H8s this weekend and take a bit off the braking and see how they do.

These pics are the OEM after a day running at 95%. The H8s measure about the same after one hard day.

I'll try one of the ones you said next.
