Project SC300 Road Racer: Part 22 – I Missed Winter…

And here’s the fully assembled rear.

Man, it took a lot of work and time to get to this point! But things were finally coming together. It was finally, after many months, time to put on the new brakes!

Actually, one thing real quick.

You might look at this and freak out thinking “what the heck? Why doesn’t this thing go all the way in?”

Don’t worry, it’s right. Remember that the suspension moves all around and that these arms articulate all around, too. In the OEM setup that has a little grease boot, you don’t notice that there’s a big gap here. But that gap needs to exist so that the surface of the rod end doesn’t contact the surface of the knuckle as the suspension articulates. Don’t fret.

OK, really, now it was time to put on the StopTech brakes.

 

StopTech instruction sheet with warning about how to wash rotors
StopTech makes it pretty clear that you need to wash and clean the rust inhibitor off of the rotors.

So, let’s get in the tub!

These rotors are big. My sinks are small. This is a sloppy job.

I actually couldn’t fit the rotor in any of the sinks, so I figured, why not the tub? It’s a big basin and I’m just washing stuff down the drain either way, so why not? As instructed, I then used a clean towel to dry things off.

It was now time to bolt the adapter bracket onto the front knuckle.

Remember all the goodies that came with the brake kit? A little bit of thread locking compound was included. As per the instructions, the OEM bolts are used to secure the adapter bracket to the knuckle, so the thread locking compound goes on them. A little dab will do you.

  1. I would add one thing about bumpsteer. I learned a lot about bumpsteer on a wet AutoX track (the hard way), that I had no idea was happening in the dry. (The bumpsteer came from swapping Upper Control Arms on a EG6 Civic from Driver/Passenger sides in an effort to increase Caster, which is a horrible idea, and totally creates massive bumpsteer.)

    If you can drive under wet conditions in a wide open parking lot with cones (ideally, not during an AutoX), I would highly recommend that you do it. Because, dry tracks can mask a lot of ‘issues’ that only reveal themselves under non-ideal, slippery driving conditions. Anyway, it’s better to learn about the effects your suspension/handling adjustments in a controlled environment, rather than during a race.

    Don’t be like me, and don’t learn the hard way. Just sayin’.

  2. Yes, they are good lug nuts but they are milled not forged, not a big difference in 304 stainless though. Even at 10$ the margins are pretty small, cost of production is something like 4.50 so once you get through tax and shipping the profits are like 1.25$ for the producer and 2.50$ for the dealer. Really good lug nuts though, and way more concentric than forged and capped standard lug nuts, puts less stress on the rim.

  3. Stainless lugs nuts? Strange concept to me considering stainless is known for how easily it galls. Certainly not something I would think to put on a race car where the wheels and tires will be on and off frequently. Also, because race car wheels and tires are on and off so frequently corrosion is really a non-issue. I’ve always just gone for cheaper open ended hardened steel racing lugs.

    1. The MSI lug nuts have been in service on my Subaru BRZ since 2015. I have been using with Dorman wheel studs and have yet to run into any issues with them or my wheel studs. My BRZ has seen about 300 ish wheel changes in those 4 years due to it is an autocross car and I swap wheels at or before events and after.
      With that said i use a Beta Tools hardened impact socket and a Milwaukee Tool impact for every change. These lug nuts take a beating and look no worse for their time in service.

      I used to buy muteki SR48 lug nuts but I also had to replace the every year due to galling and they couldn’t handle the impact socket. This is part of reason why why the MSI lug nuts are hands down the best bang for the buck motorsports lug nut on the market.

    2. Stainless only galls on stainless, even then, only some grades of stainless. Stainless lug nuts on Steel studs with aluminium rims wont gall.
