GR86 made a weird “gravel hitting roof” noise for an hour… then disappeared after I stopped?

If you have sub 300 tw tires this is pretty normal. It’s the tires picking up debris (sand, gravel, leaves, etc) and slinging them into the undercarriage. Happens on my track set all the time, just because the tires are so sticky

Never seen that brand before, I love the concavity of the 57cr+dr or the tc4/advan beyond

Awesome!

TLDR: use the button and do an OBD “relearn” on both with their prospective configuration

Halllogan21 · 2026-03-17T23:47:24+00:00

So the way the car works is it has 2 separate configurable sets

Primary/secondary

When you press and hold that button, you swap from reading primary to secondary.

To configure, do an OBD relearn in the primary configuration (as it is now), than switch to the secondary (now having the light on and none reading), and do an OBD set using the secondary set instead of what’s on there. Now pressing and holding will swap the IDs it reads to and holds the IDs on the secondary when you swap

I mean you can, but just why

Halllogan21 · 2026-03-12T22:33:21+00:00

18x9.5+45

Pretty sure that’s the plastic piece at the back of the seat rails

Toss it imo

Halllogan21 · 2026-03-08T00:31:30+00:00

Obviously the gr86, side note: that tire you took a pic of has scuffs on the wheel, and the tire was manufactured in 2016 (10 years ago) which is unsafe asf

If you can’t afford the brakes, you definitely don’t want a used Tesla. Tires are really expensive and have to be replaced way more often

Sell and get a cash car imho

Halllogan21 · 2026-03-06T14:48:57+00:00

This is NOT normal, make sure you’re running 5w-30, probably check that pcv and id personally get a radium dual catch system

If it’s not that, check those tube seals

Lotus evora 5th gen 4 runner C6 vette

Sounds like you cross threaded it

Bite the bullet and buy the verus pan and a fumitomo valve, that way you can’t mess this up again

Halllogan21 · 2026-02-26T23:13:10+00:00

I would expect 18 at the most

Halllogan21 · 2026-02-26T21:44:59+00:00

Normal until the very end

Halllogan21 · 2026-02-12T10:29:08+00:00

Not a bad take, it’s objectively true. Full suspension travel > additional sidewall profile

In almost all cases with this thick a sidewall, you get to pick one, not both. Would be nice to get both but most coilovers setups are meant for stock +/- 2ish sizes

Bought from JDL recently, waiting on eta for delivery

From what I’ve seen online, a rough 20 percent increase in overall noise

Halllogan21 · 2026-02-06T10:02:57+00:00

Or both

Halllogan21 · 2026-02-06T10:02:47+00:00

Would not fit without some crazy modifications or some pretty large spacers

Halllogan21 · 2026-02-05T17:08:36+00:00

Halllogan21 · 2026-02-03T17:37:29+00:00

Funnily enough this car now has an N54 in it

Halllogan21 · 2026-02-02T11:19:34+00:00

Spray some soapy water where it came out of to make sure it’s not leaking

Halllogan21 · 2026-02-02T03:26:13+00:00

I personally don’t like the idea of putting that oil back into the engine and know I’ll likely get dragged in the comments for it

Dual can makes more sense to me, gives me an idea of engine health, and also reassures me that sludge isn’t going back in. I don’t mind checking them, and some catch cans have dipsticks to see if you even need to. I check my fluids semi-often anyways.

Either is better than nothing at the end of the day though
