API SQ For sure use an API SP or SQ engine oil.

This is very accurate - based on 1000’s of oil samples taken by blackstone, speed diagnostics, and the top engine builders. The frequency of oil change is #1. All engine oils start to degrade after 2000 miles. If you change your engine oil after every 2-3 track days 2-3k miles, once a year...

What tire pressure cold where you running front and back on the 265/35/19 Continental Extreme Contact Forces?

So the windshield washer would probably be not enough capacity - probably a 1 min max of spray. Maybe if you are drag racing, and need it cooled for short period of time. I use about ~2.5 Gallons of water for a 20 minute session on track and usually have it running about for 10 min after on...

Okay here is what the data looks like - on the same track - same exact 2nd lap - same location where engine temps spike braking before turn - heater on, A/C Off, recirculate on, fan off. 0W-20 Pennzoil Ultra Platinum vs 5W-30 Castrol Edge Extended Performance. Pennzoil Ultra Platinum 0w20 is...

Tested water mister at COTA, and you can clearly see with it off in a cooler day it ran hotter and on hotter day it ran cooler with mister on. With Mister On, Lap 2 86F Amient Temperature = 215 F highest water temp recorded Previous day: With Mister OFF, Lap 2 78F Ambient Temperature = 228 F...

Your Aluminum will slowly come down, as this is engine break in. It will take you the first 10,000 miles to fully flush out your engine.

Quick update on Castrol Edge 5w30 extended during 20 min session racing at COTA. Castrol edge extended is a thinner 5w30 energy conservation spec. I did notice, ticking in engine was reduced. Today was a much cooler day on COTA, and will need to compare engine temps, and tomorrow should be...

Mobile 1 EP had amazing results. Check the Data in this thread of a user running 0W-20.

Quick update, I'm very surprised, but it seems this New Formula Pennzoil Ultra Platinum 0W-20 is absolute trash since they changed the base stock away from gas. With only 1,700 miles on the oil and two track days, some things I noticed, was the oil was much more brown on the dipstick than all...

I am on stock suspension, but I had modified my wheel liners with sound insulation so they were sagging. Others on completely stock did not have rubbing. But with springs, rub could be an issue. I personally don’t like lowered cars, due to decreased ground clearance, and most ruin the...

The bottle looks really cool and the price is not bad for a premium synthetic. Curious how much different the formula is vs the new Philips 66 Valor Shield which made the previous Honda Ultimate Synthetic ( now discontinued ).

Also one other massive benefit of installing 265-275/35/19 on the stock rims is - there is way more - a massive selection of discounted inventory on tirerack vs the stock 265/30/19 Same DWS is cheaper in 265/35 and 275/35 vs 265/30

Actually you make an excellent point, on track in Type R mode with the 35's zero issues, and tire wear is very even also. When I was on 30's it was too bumpy, and very difficult to manage even wear across the tire even with -3 camber in front. Road bumps, etc are a non issue. On my 4s I would...
