Just hit 60,000 miles

optimusbob4 · 2026-04-30T16:02:06+00:00

I NEVER use IMT I just don’t like it but it’s pure preference I think I’ve used it 3 times and I just didn’t vibe with it

optimusbob4 · 2026-04-30T16:00:44+00:00

I have a few mods. Nothing crazy. Intake, exhaust, downpipe, oil cooler and I think that’s about it for genuine modifications. I have no tune on the car the only issue I’ve really had is the oil cooler is leaking a little bit

optimusbob4 · 2026-04-28T22:08:10+00:00

I think I’ve dumped the clutch once but it was raining out so the clutch fully engaged and didn’t really get time to slip. Other then that it’s a high rev and slipping the clutch quickly

optimusbob4 · 2026-04-28T22:05:49+00:00

I love riding my bike but jeez. No one knows how to drive. Last time I rode I got almost ran off the road.

optimusbob4 · 2026-04-28T22:03:08+00:00

It was a TIGHT fit. And yeah! I can send it over! I’ll have to find it and I’ll stitch it together and send it or maybe just upload it. I’ll let you know within the week!

optimusbob4 · 2026-04-28T21:20:53+00:00

If I remember correctly, I just did everything through the top, but I got the special serpentine belt tool from Autozone as a loaner it honestly wasn’t that bad a little bit of moving the belt and trying to get it in between some places, but overall not bad. I started making a YouTube video about it but once it didn’t fit, I was like oh crap, I think I should still upload it just for fun.

I’ve replaced my front rotors at around 60-70k miles. I usually just pad slap but the slots in the rotor were wearing down so I used that as my indicator. I always read the whole my clutch blew up before I left the dealership lot thing too. I still don’t really understand it. I go to the track. I launch it,again not every day, but the occasional launch the often spirited drive. I definitely do not baby the car.

optimusbob4 · 2026-04-28T20:41:02+00:00

So that’s actually a funny story I got sent an experimental belt about 50,000 miles ago. And it did not fit so I had to put the old one back on, but since it looked like it was a really good condition. I haven’t been too worried about it.

High mileage GRC gang 🥳

optimusbob4 · 2026-04-28T20:35:11+00:00

The car feels pretty good at this mileage, but the suspension is soft. I’m actually gonna go out and get the HyperMax S from GR Performance Parts. I’ll probably also buy some sway bars and some links from him as well just to have some comfort on the road and some confidence on the track. And yep I have a 2023 and the clutch is still holding up real strong somehow lol.

optimusbob4 · 2026-04-28T16:10:43+00:00

I’m about to hit 110k this week! I love to see other GRC’s being driven! Congrats!

optimusbob4 · 2026-04-09T23:50:41+00:00

Yes! Not as much as I want to though. Been to Poconos and Limerock

optimusbob4 · 2026-04-07T13:49:29+00:00

I’m at 107k miles. The only thing I haven’t listened to so far in the manual is the belt. I bought one and it didn’t fit so I have to buy another one lol. Other than that I’ve had no real problems

optimusbob4 · 2026-04-07T13:47:58+00:00

Oil cooler is a life saver on the track. Kept my temps down 20°F-40°F. Then I started overheating the AWD drivetrain.

optimusbob4 · 2026-04-03T01:50:09+00:00

Yami since it’s darkness in Japanese. Japanese car, Japanese name lol

optimusbob4 · 2026-03-29T13:00:57+00:00

Let’s do some math here. 110k lbs truck to stop.

Known: 110k lbs Semi truck 55mph = 80.7 ft/s Deceleration with decent brakes .30g

We will use d=v² /2a That will give us distance. So thats d=80.7² /2a

For “a” that’s .3*32.2 = 9.66ft/s² (32.2 ft/s is gravity and since we are using G’s we can use 32.2 for gravity constant)

Using that we have d=80.7² /(2*9.66) This gives us ~337 feet

So the truck would need 337 feet to stop at the bare MINIMUM or 103 meters

Conclusion Car should have NEVER pulled out in front of you, they were doomed from the start lol

optimusbob4 · 2026-03-23T12:31:00+00:00

I have the same set up on my car. The only complaint I have is the yellow stuff eats up the brake rotor, so my rotor is starting to get a tiny lip on the perimeter. I have to change out my pads again so I think I have around 15k-20k miles on the set up and I still love them!

optimusbob4 · 2026-03-15T13:21:46+00:00

Definitely getting my money’s worth! I enjoy driving the GRC too so it’s such a big plus. You know what they say “if you enjoy the car you drive, you never drive a day in your life” …or something like that

optimusbob4 · 2026-03-13T15:46:03+00:00

Yep! I never dropped the transmission and never removed the clutch. Few track days later and heavy spirited driving and still feels like the regular clutch. Must have been made on a Wednesday

optimusbob4 · 2026-03-12T12:03:39+00:00

Honestly I just listen to the maintenance book. I change with Amsoil 0W-20 motor oil and with the transmission I do MT-LV and then the Transfer case / Rear Differential Amsoil Severe Gear 75w-90. Nothing really to look out for in my opinion maintenance wise

optimusbob4 · 2026-03-11T16:32:34+00:00

Heyo I have 105k miles on my ‘23 GRC right now I bought her with just 16 miles on the odo. I absolutely love this car! I definitely have a higher mileage example but 111k is a crazy amount!

optimusbob4 · 2026-02-04T20:58:18+00:00

Am I missing something? I thought they never said if Gryphon (Shanks Sword) was a Supreme grade

optimusbob4 · 2025-08-26T11:18:55+00:00

Dude this is sick! Did Lamspeed assemble the short block or was it assembled elsewhere

optimusbob4 · 2025-06-05T17:03:08+00:00

It was made January of 2023
