How could that work, points-wise? As long as I take at least third each day, even if Todd wins, I'm still going to have more points than anyone.

I only made 164whp with OFT Stage 1 tune at the NASA dyno (Summit Point).

In this case I am opting to dyno reclass and take the 2850lbs min weight.

I tried TTE trim and would have been very competitive with the Miatas (there were 2 other instructors there who couldnt TT that weekend either) with literally a few tenths apart, my challenge was I blew the damn stock shocks again (third set) with fluid and noises all over the board.

Hence TTD:

1) 17*9 ET45 RE71R (back ordered at Tire rack arriving July 16th) 255 sized +4+1= 5
2) MCS Doubles non remote +3 (arriving today)
3) 550/550 springs with vorshlag plates and rear mounts (arriving next week) +2
4) TRD sways installed +2
5) APR GTC200 rear wing +4
6) APR front splitter +3

No point mods:

1) rear subframe insterts
2) short shifter
3) autopower rollbar
4) seat/harness
5) Perrin oil cooler

19 points dead on with 2850 comp weight to go.

Chose to run aero vs Hoosiers for two reasons. I only have one set to play with and it does rain a fair bit.

No power mods because I want to wait for rules change to see if I get to play in TT5 or 6.

Be interesting to see data. Per Jason at Vorshlag be a very close call by running aero and RE71 (better for faster tracks like VIR) vs no aero and Hoosiers. Time will tell. First event in Aug at VIR with NASA.

1) What are you guys running for camber? I am expecting -2.2ish at the back (non adj) with -2.7 front.

2) What about the ride height? will run 1.5 inches lower both front and rear.

3) Anyone has tried the new Toyo R888R or the BFG 1.5 Rival S? Feedback? asking as I can run either in 255 for same points.

Cheers,

Lutfy

With a good bit of stripping (rear almost cleaned out) and adding the rollbar without me in it car is at 2729lbs. I am at 200 even. Comp weight is 2850 (dyno reclass). Changed driver seat to Sparco halo but with slider/seat mount/VAC base plates barely saved anything. This car is super light from the factory (unlike previous BMW's I have stripped).

Going to install the wider wheels/tires net net be same as the current stock setup on 215 Azenis+. May take the passenger side seat before weighing again (corner balance/align).

Vorshlag and MCS has been great to deal with.

Spoke with Greg, R888R not listed in rule is OK for 4 points like rest of 100wear tires as RE71R is on national back order.

Anyone in Mid Atlantic coming out at VIR next month?

Not for the season, just a heads up, Mano a Mano who's faster for the one day. 😀

Ugh...I'm not feeling so confident. My best out there last weekend was in the low 12s IIRC. What did you manage?
Shall we start the trash talking now?

2:11.1 was my fastest on my dead RE71R's. I've got a new set of RS4's a ncoming. We'll see how fast or slow they are soon.

Yeah, get the trash talking started, its a slow day at work, I need something to read

I dont know how quick the RE71Rs are myself (havent run them), but you can expect grip levels similar to nitto NT01 with the RS4, so probably not too far behind (at least should be better than heat cycled stones).

Re71R are faster than the NT01. They run good till the cords (both tires). Had the RS4 on an e36 (students car) and the grip is not comparable. Will wait for feedback as well.

For the same points I went with R888r as Re71 are on backorder. Will report the same the following weekend (testing) at Summit

Well it sounds to me like you're a couple seconds faster than me. I've got a lot of ground to make up!

Wait...I mean, uhhh....Robbie, you don't stand a chance. You seriously think you can hang with me?

Spent a good bit of time over the weekend dialing in the car.

Height 13.5 front and rear. Front camber -2.7, rear -2.2 0 toe. Lots of corner entry understeer (slow speeds), high speeds the car had corner entry understeer with corner exit oversteer under throttle. Toodled around a fair bit with the dampers and later on threw the rear wing. It MAKES a difference for sure (need front end grip desperately, be putting the front splitter this weekend).

Even with the skinny 215 street tires, was able to clock 1:29:4 which is a full second faster over stock suspension.

Tire temps clearly showed f and r outside tires almost 20 degrees higher!!

What are you all running for camber and height? Am thinking of dropping to 13 inch f and r (to maximize rear camber as I dont have the control arms) and dialing the front up to -3.2

Lastly whats the take on running E85? Any issues on track? Have read fuel starvation. Car needs power now. Min required hp is 180whp and I am at 164 currently.

First time event VIR in 2 weeks. Be running 255 R888R then.

PS: BIG THANKS to Edgar Morales of Group E Motorsport (TTC contender) for the build out/data/track support.

-3.8F and -3.2 rear on camber, 0 toe rear and -0.1 toe out front. Height is around 1.5" lower front, 1" lower rear than stock. I need a bit more front-end grip on low speed corners, car is pretty neutral on high speed corners. I think of dropping rear camber to around -2.8 and see how that works. Might add bigger rear bar.

Is this High Plains you're talking about? And if so, what's done to both of your cars if you don't mind me asking? I dropped a (gps-timed) 11.3 in my stock '17 PP with RE-71s on it last Wednesday.

Yes, High Plains. My 13 has a set of MCS coilovers, GC camber plates, 17x9 RPF1's, DTC 60 F/XP8 R pads and 245/40/17 RE71R's. Best time run on that setup was a 2:08.x last fall. Timed with my Traqmate.

Hey Trippin', I watched your video. Thanks for posting.
My car has AP Sprint with DTC60s, T2s and Maxxis RC1s. I'm not happy with the T2s, though. I think I should go with something a bit softer than the 400 pound springs. And I think I want springs that are stiffer in the rear than the front.

Nice! Thanks for sharing setup and results. Sounds similar to the STX-prepped car I followed last week. That was my first time at the track, so I'm feeling pretty good about 11's.
