    Have a look at the equivalency chart at the bottom of this page and and the graph here. I would probably target XP12 all around or XP12 front, XP10 rear then go a higher compound if you do not find them sufficient. Right now I am on Ferodo DS1-11 front and rear on the BRZ and love these pads. No fade whatsoever and they last a long time.

    On my MS6 with Nitto NT01 or stickier, I loved Endless N05U but could not find them anywhere once I went through the set that came with the PowerBrake BBK. Then I ran Carbotech XP20, Cobalt Friction XR1, and Ferodo DSUNO, each with good results but those compounds will most likely be too much for the tires you are running.

    perfect i will have a look! thanks for the input. ms3 is heavy and will generate alot of speed quickly ive noticed, specially at my home track so stopping power is something i need alot of. i would like to be able to brake later as i know the corner speed limitations of the car and i know what happens when i exceed those :rolleyes: would just like to carry my max speeds as deep into the corner as possible

    The rubberized pipe insulation from HD works for the sides of the radiator if you cut it down (in halfish) and work it in with a screwdriver. Also works to seal up the sides of the FMIC.

    Have you blocked the OEM intake pipe inlet right above the radiator the passenger side? There is a spot on the drivers side as well.

    i havent had the bumper off in sometime, but this is going to be a project i plan to spend a few hours on next week when im off work for the week. ill have to take a look, see what needs sealing and go from there i guess?

    hit the track again saturday for some more lapping with some tips for things to try from my instructor and shop. Braking significantly later, and harder, practicing some heel toeing, and overall running a tighter and more consistent line helped me shave off over 4 seconds from my previous best time, which at this track is a huge improvement in time. i think the biggest difference was in my self confidence. it was 35c (95f) out so it was very hot, coolant temp spiked 115c(239f) but the car pulled hard throughout the day. grip level was about as good as it can get from my RE71R tires. the 3 degrees of front camber from my corksport camber plates makes a HUGE difference. heres some footage i captured, camera mount on my head is less then ideal, i guess im too tall. will have to figure out better mounting i think !

    Those are some pretty high coolant temps. I would definitely look into getting more airflow thru your radiator. Genpu's bumper is a little better at directing flow thru the radiator as the ends are more closed off, but the amount of air that passes thru is less. What is your current bumper grille layout? You should look into ducting the radiator. It's pretty easy to do and the results are worth it. YMMV performing it on the genpu tho. I've had good results.

    As for the video
    1. Has that auto club event ever heard of pointing by (stupid civic trying to drag down the straight)
    2. They let you on course without a helmet ??? :eek:

    Peak coolant temps are very high I agree. Usually peaks 112c and hangs out around 106c but that day was very hot. I need to do some ducting. for sure. Currently from bumper area is stock.

    Point bys are a thing for sure, I know I do it, the guy in the s2000 signaled me by, but some guys either don't know the rules, want to drag race, or are just a**holes. Guy in a 450whp sti definitely didn't give me any point by which he should have.


    As far as helmet, during a timed event it's 100% necessary. During open lapping days however it's only recommended and not forced.
