Thanks! I bought the car used with 800 miles - already had the cage in it. Ill look up the cage when i get back from vacation - they guy included the receipts for everything! Ive been to Thunderhill twice and Laguna Seca once with this car already. Will try to find some videos from my Garmin Catalyst and upload them. My last track day at Thunderhill wasnt that great as my front right tire got heat cycled too many times and I dropped from 2:06ish Times to 2:20, to 2:25, to 2:30…. Couldn’t keep up with a GTI in the end, that was embarrassing! Haha. So much understeer. Will get new tires and an alignment before the next track day.Noticed in your build you have a roll cage and wondered it you have the Watson Racing one or had a full cage built? We definitely all hope to see some videos when you get to the track --- great looking Beast!
Hey! I see you’re in SoCal - im up in the Bay Area in Pleasanton, CA. I bought the car used from San Diego though - maybe you saw it when it was down there?If this is the same one I've seen driving around my current neighborhood, hit me up! Great looking ride!
Ah okay, I'm just north of LA. There's another one driving around here that looks just like yours.Hey! I see you’re in SoCal - im up in the Bay Area in Pleasanton, CA. I bought the car used from San Diego though - maybe you saw it when it was down there?

I fail laguna 103db days as well as at thunderhill if they’re measuring that day (which has happened once). The car automatically goes to “track” exhaust if the load on the engine is great enough. This includes WOT obviously, it also partial throttle if heading up a hill (i.e. laguna).did you have any issues at laguna with sound?
I have a 2020 GT500 Handling Pack. I've gotten lucky so far with the sound restriction at Lime Rock Park 86db. (Connecticut). I mainly ease up on the throttle coming passed the tower for the first 2 sessions of the day. Planning on adding front and rear aero in the off season. Other then that the suspension is done and I'm running 315 Hoosiers R7 on Signature Wheels.I fail laguna 103db days as well as at thunderhill if they’re measuring that day (which has happened once).

Here’s a fix: There is a fuse for the exhaust valves, put them in sport, and pull the fuse and they will stay in sport. This was enough to pass 103db At Thunderhill. I haven’t tried this at Laguna yet.
warning on fix: I don’t really know if this is good for the engine. I assume it pulls timing and limits power since the exhaust isn’t fully open, to avoid damaging itself… but I don’t know. Also, when I put the fuse back, it took a few key cycles to make the valves work properly again. They seem fine now, but that made me a bit nervous
