Hey @srproductions, great thread! I have some questions about your braking setup, I'm super amazed and would like to mimic similar results.

Which size ST40's are you running? 328mm or 355mm? I assume 328mm so you can stick with 17in wheels?

And what about on the rears? Stoptech 322mm?

Also do you run venting from the brake ducts to the rotor dust guards? Can you post some more pictures of your set up?

Sorry for all the questions, I'm looking to upgrade my brakes at the moment and have had something similar to your setup in mind!

 

Thanks!

I am running Stoptech ST40 328mm. The rear is a stock caliper with Urge 2 piece rear rotors. I run ducts to only the front rotors and have a Wasp kit that is no longer made that directs the air directly so the cooling channels in the rotor. The rear is not vented but I will vent them this winter. The rear wears faster then the front. Hopefully ducting helps.

I got a excellent deal on the ST40 kit from Freddy at P-Tuning. You really can't beat Stoptech and they are an excellent value.

 

On a side note, my NSX restoration is coming along nicely! Should be on the road within a week!

 

I had an excellent weekend at Summit Point last week. I was really excited leading up to this event because the track was freshly paved and I was trying Hoosier R7s for the first time. I got a cheap set of R7 scrubs for $150 and they worked well. My best time here was a 1:23.7 on RC1s and I was able to cut a 1:21.3 after the repaved and R7s. The time was faster then the official TTC lap record there but I was stupid and spun on the next lap so it counted as a DQ. I am confident the car will run 1:19s there in TTC trim on fresh hoosiers.

It was pretty cold this weekend with temps ranging from 20-40 degrees.

The season is over and the will be getting some changes I'll highlight in the next post!

 

Pics from last weekend. This really shows how awesome this car is. I drove to the track, ran all weekend, placed 1st both days, and then drove it home stopping in a small town for dinner!

I saw this picture of my car on the track and the rear looks totally collapsed. I am running AST4150s with 700/650 springs. They are 5 years old now. I was lucky enough to win a bunch of AST contingency and will have them rebuilt my shocks over the winter. I am going to put new springs on with the same spring rates.

It's tempting to change to something new and exciting but this suspension setup has worked for me very well for a long time. The really enjoy how it drives so I am going to leave it exactly the same and just freshen it up. I like single adjustable because it reduces setup variables. No need to change something that works!

 

There is a ton of information on this forum about a number of components. Here is a run-down of what I used, how long it lasted, and my thoughts. Hopefully this information can be helpful to people doing new builds or changing up parts!

Total miles from when I started the build to my last track day last week was 4,400 miles. I did 16 days on track and 65 total sessions. These were a combination of TT sessions (15 min) and HPDE sessions (20-25min)

This car is street driven only to and from the track.

Engine:

PLM Header, AEM V2 intake, high flow cat, T1R-ES Exhaust. I dyno’ed the car at InlinePro and it made 214RWHP. All these parts worked well and have been documented to make power for years. Maintenance wise I used Castrol 0W40 that I purchased from Amazon. I did oil changes every 1000-1500 miles and every 3-5 track days. I sent my oil off to Blackstone and everything came back healthy and they advised me I can go longer on my changes.

Cooling:

Mishimoto Oil Cooler and radiator. Both worked fine, no issues, no overheating. Not much to say here.

Braking:

I keep track of days and sessions on my pads, rotors, and fluids. My setup is as follows:

Front: Stoptech ST40 328mm BBK with APR cooling ducts. Carbotech XP12 pads.

Rear: Stock with Urge 2-piece rear rotors. No cooling. Carbotech XP12 pads.

Fluid: Castrol SRF.

The Castrol SRF fluid is just incredible. I didn’t change it all season and it never required bleeding. I used Motul and ATE in the past which worked ok but required bleeding every weekend. Spend the money, Castrol SRF is well worth it.

The braking system on this car is just incredible. I found running XP12s all around to give me the best balance on this car. Here are the stats:

Front Rotors: 63 sessions. Plenty of life remaining.

Rear Rotors: 101 sessions. Plenty of life remaining.

Carbotech XP12 pads F/R: I got 30-33 sessions out of rears and 35-38 sessions out of the fronts.

Suspension:

AST4150 700/650 springs. This setup is 5 years old and has moved car to car with me. Works very. It is time for a rebuilt now though. I will just be rebuilding them and not changing anything because I am very happy with their performance. I use them with stock sway bars.

Wheels/Tires:

I bought two sets of 949 Racing 17x10 6ULs this year. One for my RC1s and one for my Hoosier R7s. They aren’t the best-looking wheel but they are light, cheap, strong, and fit the S2000 perfect.

MAXXIS RC1: I’ve used NT01s on all my track cars for years. They are an awesome 100TW tires you can drive on till they cord. There are no heat cycle issues with them and I always drove to and from the track. I would get about 8-10 days out of these. I was hesitant to try the RC1 since NT01s worked so great for me but I am happy to report they are a as good and maybe slightly better tire then the NT01. I have 2800 total miles and 39 heat cycles on them with plenty of rubber remaining and no degradation of performance from heat cycles. I am very impressed by their longevity. They have to be driven a bit tidier then the NT01s but I think they are marginally faster by maybe .1-.3 seconds. Also, Maxxis has excellent contingency!

Hoosier R7: Not much to say here since I just used them for the first time this weekend and I was on scrubs. They are 2 seconds faster than at the very least compared to RC1s at Summit. The grip is unreal. These help me secured two 1st place finishes last weekend which got me another set for free!

Trans/Fluid/Diff Fluids: Just using the standard stuff here. SRF for the clutch, Honda MTL for the trans, and Mobil 1 for the diff. All fluids swapped out at the beginning of the season and again in the middle.

Mounts: Both of my OEM engine mounts were torn in half. I didn’t want the engine vibration from stiff mounts but also didn’t want the motor and trans to move around much. My solution was to go with new OEM mounts, Ingalls Engine Dampener, and Innovative 75A transmission mount. This setup worked great. The harness is just slightly more than stock because of the 75A trans mount but totally bearable. I have nice cushiony engine mounts but the engine does not rock due to the dampener.

Oiling: Stock pan! From my experience with these cars, just monitor the oil levels and the stock pan works perfectly well. I haven’t had any oiling issues and have had 7 S2000s now. The stock pan is very well designed and the oil pick up is extremely low in the pan. I use a Saikou Michi dual catch can that works great. I got their extension kit so while the capacity of the can is small, its quick and easy to drain without any tools.

Safety: Sparco Pro ADV driver seat with PCI fixed bracket. This seat and bracket setup work great and I was able to install it without modifying anything. I’ve seen and used a lot of brackets and the PCI setup is my favorite. The seat is also fairly comfortable even on 5hr drives to the track.

Aero:

I ended up taking the splitters and canards off for points. They were cheap and flexiable and I noticed no difference with them off or on. I went with the J’s racing replica wing they sell on ebay for about $700. This wing is really high quality and works great! Other then my hardtop, this is the only other replica part on my car. I couldn’t justify spending $1500+ on a real wing when this one works the same and is good quality.

On to some picture and video whoring!

Last weekend at Summit. This is the S2000 lap record here. It was also going to be the TTC all time lap record until I spun and DQ’d in the end!


Little NJMP action. I was within .7 of the TTC lap record here that was set on Hoosiers. My car was on RC1! The record should be easily attainable on Hoosiers.

 

Nice List of owned cars! makes me jealous ... I may have to try your rear brake setup once I go to get new brakes. Have the stoptechs up front and love them. Work great with my S/C. what was the 700 dollar rear wing you got off ebay if you dont mind me asking? and Did you swap out after some time to a voltex it looks like?

Also the car looks great especially in motion!

 

The wing on the car is a Voltex replica off eBay. Just reach 1600mm carbon fiber wing on eBay and it shows up.

 

Do you find yourself wanting some sort of front aero to balance out the wing? Does it feel like there's a bit of push that you can't dial out with other suspension/alignment settings, or is it just right?

 

I do have some front end push at high speeds. Front aero would be beneficial. I will be doing vents and a splitter hopefully if the TT5 rules allow it.
