Track talk modifications

[kitkat]

How are the Project MU HC+ going. Seriously looking at trying them, Would you use them on track?

They've been going well and I would compare them to OEM pads -- no I wouldn't recommend either at the track.

 

[BruceN]

I propose to have a new forum listed to help those tracking their cars, or those who may want to track, learn more about what the Emira is capable of on the track in a safe environment. It should be a forum that lists modifications, show pictures and videos. Discussions will help everyone build their level of track car and with practice become a better driver on the track that will make them a safer driver on the raod.
If it happens, we thank you!

great idea, thanks for starting this

What is everyone using for harnesses? I typically prefer 5 or 6 points, but I'm not keen on drilling holes in this chassis. I saw the 4 points that are apparently FIA legal on GRP's site. Is that the general consensus for the optimal harness?

4 Point Schroth ASM is what I have used for the last 15 years. If you don't want to daily in an uncomfortable race seat, the ASM is the way to go. Just make sure to adjust it and tighten it so the lap belt is as low as possible to keep the force off your organs in case of a crash, but to also keep the shoulder belts tight so you don't break your neck. And while I have the floor, years ago Ron at Discovery Parts and I were waiting to get into Barber on a Friday night and he told me that if you have a face shield on your helmet and air bags, not to leave the shield up because if the air bag deploys and it hits the shield, it can result in serious neck damage.

Good to know, thank you! I typically wear a Hans device when I plan to push it. Sounds like you live in the Southeast? (Unless you were the one who made the Georgia post a while back, I can't remember)

 

[crainp]

Yes, I'm in the Pensacola area in the winters, N. Idaho summers. Hans for sure. I sold both race oriented high horsepower Nissan GTRs recently, and will track only the Emira, mainly at the Spokane track, Qlispe RP, (The tribe bought it a few years ago), as it is only an hour away and doesn't involve 4 days out to do a track weekend. I have a harness bar coming and will be using that with one of the ASM's from one of the GTRs. Fortunately, the Emira has a built in roll bar. I am hoping that AP J-Hooks come available before I need new rotors, otherwise will get a set of Girodiscs. I ran Hawk DTC70 front and DTC60 rear pads, and am running the same on the Emira.

I have the 4 that I use with my Hans, but the 5 or 6 would be better if you track. Going with the 2 inch wide 6 points so my boys get a break when I install the Tillet carbon seats, which are comfortable, but get the wider ones that GRP sells. Can't wait to see your dyno results w/ the VF tuner lid. Glad to see temperatures are down because it loves to go into limp mode if it gets tto hot.

I have XL Tillet's on the way. So you aren't using 6 points currently, but you are about to switch over? I assume that means you'll be doing some drilling then or is there an alternative solution (such as tying them into the seat mounts)?

I'll keep you posted once we have the lid on the dyno. The iATs were from the Burger Tuning Data Pulls and could have been due to a few factors, although weather and temp were in a similar range. I think more comparisons will be needed to understand the impact fully. I haven't had any issues of limp mode so far (knock on wood.) We'll see how it goes on track this summer in South Georgia.

GRP Harness Bar and schroth FSE 4pt

 

[Tracked Emira]

Greg will have to let us know what needs to be done and what parts are needed because I will want a 6 point harness for sure.

I really hope the rollover bars in the Emira are appropriate as if the roof caves you will break you neck being harnessed into a seat.

Thanks, so the Pagids for the win all round?

The car frame has roll over bar protection. Who's got the pictures?

I really like the rsl29 for track use — obviously I’d never run them on the street personally.

i ran them to and from the track with great success... my favorite compound these days... I'm sure there are better but it has a really balanced feel and stopping power with modulation. never went off track due to fade. was very predictable.

As we approach summer and the track season starts, I put the RSL29s on my cars and do not take them off until season closes and winter is approaching. I have been using these pads for close to two decades. They are perfectly fine on the street during summer months. As soon as they get loud, I know I need to re-bed them in, but that's about it.

Just finished up a weekend at COTA. PB 2:32, I will be trying to break 2:30 in April, I believe there is some more room for improvement at T6 and T12.

Current parts list:
- GRP High Flow Intake filter (for the sound lol)
- Tillett B10 driver seat
- short shifter
- third cat delete
- GRP Lowering Sleeves (lowered from stock F7/16, R5/16, for a bit extra front rake)
- Front EBC SR21, Rear OEM pads
- Castrol SRF (must for track days)
- Nankang CRS V2
- MWR Oil baffle pan
- I'm using MT90 for transmission oil, personally I've been getting easier shifts.

Alignment:
Camber F-1.7/R-2.1
Caster 5.0/5.0
Toe F-0.02/R0.22

Great list of modifications! I’m interested to know how you managed a 2.1 camber on the rear? I’m unsure if this is normal parameters but my geometry guy only managed 1.5.

I’ll be doing the 3rd cat delete and GRP cold air intake very soon.

My geo guy also said he couldn't get anymore than -1.80 camber (per wheel) on the rear with the stock Lotus suspension. Factory settings with sports suspension and Cup Sport 2s is -1.80 and so that's at max. camber with stock suspension.
Maybe that -2.1 camber is total camber (across both wheels) or they have improved the suspension parts? I can't think that lowering the car made much difference here.

Lowering the car does net you additional negative camber. I'm lowered and have -2.0 in the front. Others that are lowered seems to have similar camber ranges.
