If not try jd at globaltimeattack. From reading the current rules it is not very clear. But I would assume RCAs, adjustable links, changes in camber and caster with like top mounts or an ALK type part are okay. But not, say, changing inner control arm pickups (we drilled new holes higher up in the crossmember on our mod/ltd subaru).

SpaceRangerJoe posted:ABS doesn't work. I'm pretty sure it's a bad pump, or more likely the wiring in the pump. It's on the to-do list. I can drive and manage to not lock them up, so I just wasn't in a hurry to fix it. -3.5 to -3.8 degrees of camber is a lot for nt01's, the big front bar should help a lot. Maybe you need a bigger bar out back to make it understeer a bit less? But with that amount of camber, you're really only braking with the inside shoulders of the tires, which means a lot less contact patch, which means abs engages sooner/you lock them up sooner, etc. You can get away with that much camber on hoosiers/slicks because they just have so much grip under braking, I haven't seen any "street" tires come anywhere close to slicks under braking still. Street tires always feel sketchy/unstable with maximum braking compared to slicks, so a lot of people run -2.5 to -3.0 camber up front with "street" tires and just do more with sway bars and spring rates to optimize tire wear instead of compromising braking performance. I am calling nt01's "street" tires because their performance/characteristics is much more similar to the 200TW's nowadays than it is a hoosier r7.

Two things I'm thinking of. Number one, had an annoying end to a race weekend when a cloudburst meant my dad put the car off the track on the first lap and spent the whole race watching stuff go past in his rear view mirror from 20 yards into a swamp, and I had to go bike around the track to figure out WTF happened when he didn't come around again. Between this and various other reasons, we're thinking about radios now - not pro grade worldbeating radio setups yet, kinda between http://www.sampsonracing.com/The-Starter-5watt-Package-for-2way-driver-to-crew-p/starter-plus.htm http://clubracingradios.com/Budget-5-Watt-Radio-System-5WATTAFF.htm or http://www.racingsafetywarehouse.com/product/600080141.html and yes I know, Chinese radios aren't going to be as good as something where I'm paying more. Right now it's between "go cheapish to prove out the usefulness" or "don't do this at all". And yes I know I'm supposed to get a license for GMRS. Secondly, I sat and looked at the run group listing for my local org (Midwest Council) and realized I can squeeze the NC MX-5 into 2, maybe 3 (though potential backmarker in the third so probably not) different run groups / races per day. Given the price of Hoosiers and their falloff, and Midwest Council not actually caring if I throw bigger wheels on, I was thinking of going with Toyo RRs. It would be 235/40/17 Toyo RRs on 17x8 or 17x9 wheels, vs the Hoosier R7s in 225/45/17 on stock 17x7 wheels. How much lap time am I likely to lose on a 1:25ish lap, and will I be able to keep that going for more heat cycles?

You're going to have to install an external antenna no matter which "solution" you choose. If you want in car radios, do it correctly the first time around.

We used that first system you linked for a couple years and they worked ok some of the time. They were rentals which didn't help but even when they were working great at a track like Road America we'd have communication for 1/4 of the track at best. Basically if you couldn't see the car you didn't have a good chance of it working. We ungraded to a powered base station with a big rear end antenna and similar in the car with a more reasonably sized antenna. Both ran off 12v then we had additional handheld units for walking around the pit and if we weren't sitting in the trailer. With this setup we could hold conversations anywhere on track. We ended up with something similar to this - http://www.sampsonracing.com/Racing-Radios-Pro-20watt-Road-Racer-Endurance-Pack-p/20-watt-road-racer.htm

I was trying to compensate for the tire wear with camber. Someday I'll get back to the track and see what the new front bar does. I can pull the shims from the front struts to lose about half a degree of camber. It will be 2018 before I'm back on track, but I'll remember this. Thanks again!

You can do that, most plans have unlimited minutes these days anyway. But you need decent cell reception all the way around the track. We had radios, it was really nice to be able to tell the driver about traffic or problems on the track etc, especially since the car could only do about 2 flat out laps per session.nollij posted:I have Race Fab LCAs which have adjustable camber/caster/RC.

From experience, Blackhawk Farms has lovely cell reception around a lot of it. Ordered a setup using HYT radios. It might prove to not be good enough, but it's a place to start.

Just keep in mind you're playing pirate radio with just about every race radio system. That linked system will be stomping on HAM bands. e: just saw the thread on MT where you asked about the pirateness of this all. FatCow fucked around with this message at 01:10 on Jun 2, 2017 |

Initial impression was lack of ignition in cylinder 1 as it was flooded compared to the others when i pulled the plugs. Replacing spark plugs and coil packs didnt do anything. Now I am considering that the headgasket popped and that liquid is gas/coolant. Annoyingly my Laptop is having a problem reading from the Tactrix ECU logger to pull the logs and see what the knock looks like.

kimbo305 posted:What do pro race series use to be legal? To be legal in the eyes of the FCC, a business (race team) obtain a license to operate commerical band equipment, usually geographically locked at the location noted in the application, usually pretty easy to obtain with low power handhelds and derated mobile radios use in racing. Then you just use the radios at tracks* and watch for stepping on others. Real teams and sanctioning bodies coordinate frequency use and can move around inside their licensed frequencies to get everyone in there, or at least on different CTCSS/CDCSS tone or whatever the equivalent is for their specific DMR system. The other way is to rent/lease radios and piggyback on the vendor's licences, which is the 'normal' way its done to circumvent the licensing hoops. Sanctioning bodies themselves do this, as well. *Note that this can be operating outside the license's geographical limitations, unless you got some serious talent working on your applications and know what tracks you will be at... edit: Its a gigantic shitshow and it really only works when everyone uses a single vendor who has an exclusive deal with the sanctioning body. Circle/oval track racing tends to have bans on two way radios, though sometimes has one way spotter communications with a Raceiver or similar receive only setup. LeMons/ChumpCar/WRL is a huge loving shitfest radio-wise and people run garbage radios all over bands that get the FCC or local emergency response really interested in the event. Its far far far worse now with VFO mode enabled "Commercial" garbage like the Baofeng UV5R and its ilk. DJ Commie fucked around with this message at 05:19 on Jun 5, 2017 |

He is good with the arms as long as they are "commercially available." As for the uprights, Tony did acknowledge that they are not addressed in the rules but now that I ask, he will add something for next year on uprights... :-(

It was the only day I've ever run on full slicks (R7 takeoffs) too. To say my skill level was insufficient for the situation was an understatement. I skipped the last session so I could drive home when it wasn't actively raining. The drive home was far more terrifying than the track. Don't forget to do solid solid diff and subframe mounts for maximum diff whine.
