I am not that good to feel a difference between one click, but can definitely feel the difference in car behavior if I go by two clicks.

The car feels solid on the track, lots of mechanical grip, everyone who rides with me compliments how good the car feels. The car is very neutral the way I have it set up.

@Opie; may have further thoughs, I do not remember what suspension he is running, but he may be able to provide a comparison to his setup.

I am running RCE Tarmac II's with 400/400 springs
Code Monkey's car was very neutral, stable and had a lot of grip. Very similar levels to my RCE setup and just a tad bit firmer.

MCS makes a nice coil over!

A while ago the transmission started to act again during a road racing session. I had trouble going into gears and had to end my weekend early. Upon inspection, the clutch was shot and there were metal flakes in the tranny. The garage space is taken up by another project at the moment so I had the Atlanta Speed Company perform the work. I usually avoid shops like the plague, but these guys are awesome, highly recommended.

Installed:
- brand-new 0-mile OEM transmission (previous one was used with 34,000 miles)
- new clutch (Southbend stage 2 endurance)
- new flywheel
- Verus clutch fork and clutch fork pivot
- new TOB
- swapped MTEC shift springs from the busted tranny

Unistalled:
- Money Shift Racing hydraulic TOB

Oooh, tell us more about your decision to uninstall the hydraulic TOB.

Code Monkey · 10-06-2020, 08:43 PM

This is my 3rd transmission so I want to take a hard look at myself and think whether I am doing something wrong. Banging gears too much, dragging the clutch, something else? I wanted to eliminate as many extraneous factors as I can, hence going back to the OEM TOB. The shop said the MSR TOB looks fine, but they recommend a hydraulic TOB for FI cars, not for cars at stock power level.

Went back to stock header/overpipe/front pipe and removed the Flex Fuel kit. Needed to pass emissions + it is time to simplify things. Got yet another check engine light, this time for the rear o2 sensor; replaced with a new OEM sensor. The code went away after a couple drives and the car successfully passed emissions.

What is the preferred tranny lube for track cars these days? I was using Pentosin but changed to Motul 300. I have since started to get a grind going into 3rd. I'm not sure if it is a lubrication or a wear issue.

Code Monkey · 10-14-2020, 01:58 PM

I have been using Motul Gear 300 75w90 but switched to Redline MT-90 75w90 for the new transmission.

Pat · 10-14-2020, 02:50 PM

50/50 mix of Motul Gear 300 and Redline MT-90 is the best I've found.

Code Monkey · 10-20-2020, 07:12 PM

Put 500 miles on the new transmission and changed the tranny fluid. The drain plug looks good.

Changed engine oil; 1,911 miles since last oil chage but almost a year ago.

Also had the Whiteline diff bushings installed (KDT924) to complement the previously installed KDT922 and KDT923.

Another oil analysis from Blackstone.

Did a read through of your ownership with this car and tracking it. Christ, the upkeep and wear.

I autocross only (a lot) and think I'll stick to that, lol.

I just need this engine to last another year or two and then do a K-swap when it goes.

This year I will do some track days in the Civic Type R to spread the wear and tear across two cars.

Removed the Essex harness bar and Schroth harnesses. Kept the original trim pieces so the interior is back to stock.

Planning to sell it? Or just don't feel like messing with harnesses anymore?
