FYI that clearance to the brake calipers is exactly what my BBS SR 18x8 +44 wheels looked like, so I bought these 2mm spacers from Australia in order to get proper clearance without sacrificing the hub centricity. 5mm puts you in a spot where the hub centric rings aren't as effective...

Just a fair warning thing: I would not attempt the clutch slave swap and the CMC damper delete without a proper power bleeder. You'd be surprised how much air makes it into the master cylinder even when you actively try to stop fluid from draining out of it. I put a rubber vacuum cap on the...

A brand-new clutch slave is $130, so they're upcharging like $100 for the delete service. That seems fair to me.

It's easier than you'd think, and hopefully the video I'm putting together has all the right details to give folks a bit more confidence to do this. Our cars use the same clutch slave as the FL5, and I'm not sure if anyone out there is selling pre-modified slave cylinders yet. There was...

The clutch pedal spring helped me on basically all shifting because the clutch pedal felt a bit more predictable, but the real silver bullet with clutch pedal predictability is to do all three. Each one has it's own effect on the clutch pedal. The so-called "delay valve" actually just slows...

Deleting the CMC damper and the CDV valve will help with that, and you might also try switching your trans fluid to AC Delco Synchromesh 10-4014, which has been widely reported to help with 2nd gear grind specifically.

This mod is great on it's own. Have you driven older cars or is this your first manual? If you've driven older cars, I just about guarantee you will love it. The "point of no return" isn't really. You will have to remove a couple of sensor connections, take the clevis pin out of the pedal...

Thanks, that's my video. Working on editing the one about the CDV + CMC damper delete as time allows, complete with data captured with 1000fps high speed video before and after. The CDV and CMC damper have a significant effect. The car feels so much more analog and natural now. Feels like it...

I am making a video on this soon, but get rid of all the silly stuff that makes the clutch pedal feel like a video game simulator. Get rid of the delay valve in the clutch slave cylinder (common Honda mod for many years now as they all use variations of the same clutch slave design.) Get rid...

Is anyone aware of a phone app or Windows app that can activate maintenance mode via an OBDLink MX+ ? That unit has been such a good piece of kit for BMW and Ford cars. FORscan (the Windows version) can do a LOT of stuff for Ford vehicles, and then there's Bimmerlink for BMWs. Doesn't seem...

We're fretting over 10mm of width here. All good winter tires will have mediocre to bad dry handling characteristics. I don't drive my cars hard when they have winter tires on. I look at it like this: what width of tire would I run in the snow on a FWD economy car weighing 3200 pounds...

If I upgrade my summer set at all, it will be to bronze but I want to go with Apex's 18x9.5 ET58 spec, which they currently do not offer in bronze. That will net a bit more sidewall for better rim protection and ride quality, and more tire options to boot, all while keeping the speedo accurate...

I wish my white ITS was spec'd with the bronze! It does look great on these cars.

Changing to a slightly taller tire size isn't going to stress the hub or alter the scrub radius (much) on these cars because the suspension design is quite different from a standard McPherson strut. If you're worried about geometry, you are WAY more likely to mess all of that up by going with a...

Let us know how you feel about the winter performance! I've heard a few good things here and there about it when used in the FK8/FL5.

Motul *does* have a trans fluid product that seems suitable for our cars: Motul Motylgear 75W-80 <-link 10.1 cSt @ 100°C 58.8 cSt @ 40°C Now, I said "seems" on purpose. Someone will have to try it to see how it goes. Is it as good as or better than GM (ACDelco) Synchromesh 10-4014? Dunno...

Not all LSDs are the same. Our LSD does *not* have clutches and as such does not need LSD additives. It is a "helical" differential that works using gearing and geometry to bias torque. In fact, LSD additive may damage your synchros and degrade their function. Do not put LSD friction...

Some more context around manual transmission gear oils. Here are the kinematic viscosities (in centistokes/cSt or mm2/s) of Honda MTF and other 70W, 75W, 75W-80, 75W-85, and 75W-90 GL-4 MT gear oils: Honda MTF (Approximately 70W but not listed as such) 7.265 cSt @ 100°C* 30.70 cSt @ 40°C *...

Bingo. No secret sauce for this LSD. The CTR folks have been having good success with AC Delco Synchromesh 10-4014. Has resolved issues for some with second gear grind, 3rd gear popout, and 4th/5th gear lockout issues. It's a common enough swap that you'll find kits for sale at dedicated...

Aeroflow Dynamics sells paint-matched flares for the VB that aren't insanely expensive, and it doesn't look quite as horrifying with them: https://www.aeroflowdynamics.com/products/2022-subaru-wrx-paint-matched-fender-flares Unfortunately there does not seem to be a quick fix of the WRX...
