Hey everyone, figured we'd start this thread since the discussion was starting to gain some momentum on the PRI thread.

Let's chat about the GridLife Roadster Modified Class.

@StableEnergies

Thank you to @KevinK121 for these initial docs.

@StableEnergies

If anyone has any questions regarding specific rule sets or anything of that nature please contact me via email ( hedianraceteam@gmail.com ). I check my email daily and can get back to you ASAP. I just attended a time attack seminar at PRI and they covered a lot of the questions that are being asked in the "PRI" thread. Another place to be able to quick answers is through the North American Time Attack council (NATA).

Looking forward to it. Still have a few things on the to-do list but at minimum, I intend to make it out to Autobahn Country Club to get my feet wet.

I sort of dislike the RM2 interior and drivetrain rules. Makes it a little harder to build a car that can run in RM2 and then still be competitive in some of the other Street classes.

Build for Street Mod, compete in that as the main concentration and then also happen to compete in RM2. I don't think the weights will be drastically different between a Track-Mod RM2 car vs Street-Mod RM2 car.

BMW trans is what makes RM2 not look great.

KevinK121

​​​​​​​Huh?

I think he means other street classes apart from gridlife. You aren't able to compete in two different classes per event with GL.

KevinK121

Trans options are prohibited in cars retaining OEM engines. It'd be cheaper and plenty reliable to source a miata 6sp for a K car or whatever else.

The intended power limit is less than 275.


I guess I dont understand your comment.

From what I believe I had read I could run a BMW trans in GTA and Grid Life street class. The plan was to have the car reliable at 350-400whp with the BMW trans. Then just turn down the boost to below the RM2 limit.
I also don't like that I have to have full carpet and interior for Street classes but not RM2.




Nothing in the GTA street class prevents be from running the BMW trans and BP motor, since I am staying RWD. At least that is how I read the rules.

KevinK121

Oh, durr. I was looking at everything from the opposite perspective. That makes sense. That and the GTA classes and GL classes being similar... it all makes sense now

Your Drunkle

Im confused by the engine modification rules for RM1. Are modifications open except for the items listed and I assume needing to be within the target HP range? Or is a "factory block engine" and completely unmodified engine?

I want to build the car to run in as many events as possible. I know 6 speed will do "fine" at 250-275whp at most tracks. Road Atlanta is a place though if I want the car to be competitive in a street class that the extra 100whp is "needed". I don't really want to have to go back and forth swapping between the BMW trans and 6 speeds.

That interior and carpet bits I can live with. It is the trans that kills future hopes and dreams.


Also do we know if Grid Life is going to force miata's to only compete in miata class?

KevinK121

Factory block engine without forced induction. Go wild and stay within the hp limits.

The FB rep basically said if its not specifically prohibited, its open. Other reps have also communicated the series is in the spirit of fun among friends and cheating/stretching the rules would be missing the point.


Yeah that makes perfect sense. And no, if you have a miata, you're not going to be forced to run with the miata classes, they just came out with these classes because it was pretty unreasonable to have a miata owner expected to compete with S2k's, boosted bmw's and corvettes.

At least I wouldn't imagine(Im going to ask now). Think you'd be better off just building for RMU with that setup? Sounds like your there anyways with them power levels.

Nah that was brought up on the Facebook page. The same fastest time of the day/event/etc can count towards your normal Time-Attack class and Roadster Modified.

This is awesome and it's been great being apart of the initial discussion and ruleset. We'll be running 2 or 3 cars in this series in RM2 and/or RMU.

We have some surprises on the way for 2019 too, should be fun.

I don't really want to run unlimited classes, as I will get out spent by everyone and can't build a competitive car. At least for the regular street classes I think I can build a competitive miata. 275whp is probably fine for all the tracks except Road Atalanta. That one needs more HP to be competitive in. So the long term goal was BMW trans in my otherwise street car so that I can crank up boost when needed.

I may just end up building for RM2 as it is. I have a 6 speed in the car currently and have a spare. So it is the "cheaper" route for the moment. It looks like Grid Life has also added a few more events on the east coast. So maybe that will be the plan.

KevinK121

Ive never looked into GTA. Sounds like GL is just a for-fun series based off of it though.

Someday maybe.

Maybe it can be written in RM2 rules to allow non-manufacture transmission swaps, but still prohibit sequentials and other major performance benefiting transmissions. I believe the BMW trans swap is more of a reliability mod vs a "this will drop 0.5sec per lap!".

I missed the stock engine only for RM2. That alone will probably make me not join in. I will be sticking to the regular TA Street class.

I would consider running RMU except for I don't have a 6 point cage and have zero desire to run one for driving on the street. Running the Ace's would be nice though.
