*The FL5 Track Junkie Thread*

Thanks for the feedback!

I've removed the rain guard, and I also run a WOT under tray. I'll try the downpipe and turbo heat blankets next. FWIW, I push the car hard. In this particular example, I was driving 2:34 pace at COTA and still driving conservatively to reduce heat stress - early shift points and lifting off throttle in certain sections.

My next step would be WOT oil cooler and radiator, but I would hate to go down that rabbit hole only to find minimal improvement bc I have a bigger problem.

I guess I’m still surprised you’re seeing those temps on the first hot lap. My temps take a few laps to climb and with the OEM setup they would continue to climb until the system couldn’t pull the heat out. I wouldn’t see temps that high so quickly but all of this is pretty dependent on driving style, temps, altitude, etc.

I think you’ll see improvement from the WOT oil cooler. I’m running HEL that blocks some airflow to the radiator. I intend to go to the WOT system over the off-season.

Only other explanation is trapped air in my radiator lines or obstructed air flow from the intercooler.

For anybody thinking of purchasing a CSF radiator:

I got a deal on a CSF radiator recently, and decided to install it before a COTA event last weekend. I used the standard Honda Type 2 coolant so I could have an OEM comparison.

The result: once the ambient temperature approached 90 degF, my coolant temp reached 239 before I could finish my first lap (not including outlap). The CSF radiator did absolutely nothing compared to OEM. Maybe it helps in cooler weather? It looks cool though...

My setup: Yokohama A052's, Pagid RST3 fronts, Hawk DTC30 rears, Adjustable ball joints, PRL intake, TSP downpipe, CSF radiator, and Mishimoto overflow tank.

Make sure you bleed really good the air pockets on the cooling systems. I seen ppl having temps issues cause of this i know @clubversion might know better about the same radiator you have. He also tracks with it in Florida.

I recently learned that A052's aren't great lapping tires...

It's a good option -- I've got 7 hard days on mine, and they are still looking great. I've run them backwards twice now just to even out wear a bit. I will be flipping on the wheels soon to get some additional life. The little wear indicators on the sidewall are quite helpful.

I've been running in 265/35/19 and it's been a pleasant street tire as well. There's probably 2K miles on them now that I think about it.

At Buy3Get1, its tough to argue for any of the other options besides the V730, but those will get dicier in the rain a bit faster.

It's not the fastest, and it definitely makes your work for the pace out of them, but they are hyper consistent and very communicative.

What tire pressure cold where you running front and back on the 265/35/19 Continental Extreme Contact Forces?

Far from apples to apples, but also recently installed the CSF radiator and WOT cooling plate. Only 1 track day since, and temps were favorable, but I didn’t exceed 218 or so coolant temps. Was able to overheat the PS4S before the coolant this time.

I'm debating between 18x9.5+45 or 18x10.5+47 Apex Wheels for the AutoX events next year. It's SCCA Solo, so typical lap times are 35-40 seconds. I'm also going to run Bridgestone Potenza RE-71RS tires. I am not planning to lower at all or pull pins; the only suspension upgrade will be the RV6 RSB. I'm looking for an option that works for the track and daily commutes until I swap back to the OEM wheels in between events.

Can anyone chime in with their experience on either wheel size?

I'm sure you're looking for direct customer experience, but I did want to pop in and say that our 18x10.5" ET47 is a direct-fit on a completely stock suspension car.

Meaning if you're not lowering at all, you can just throw those on and go. They'll give better sidewall support than a 9.5" so handling wise you could expect much sharper handling on identical tire sizes.

It'll also give you more room to grow if you decide you want to in the future.

This isn't mean't to strictly push you towards the wider wheel, but the vibe I was getting is that your concerns about the 10.5" were having to do additional modification to make it fit so that's what I was hoping to address here!

Thank you for the info! The more research and chatting with fellow owners, 10.5" wide seems to be the play; I was just worried about fitment and comfort when I'm just driving it to and from work and whatnot. if I do decide to lower it on springs, will i run into any fitment issues? Thanks!

Depends on how low you go. Some of the more mild drops that are in the half-inch range are usually fine. Beyond that you can encounter rubbing. Camber starts to get more important the lower you go.

Beyond an inch drop, I've seen more cases of rubbing in the rear than in the front so just keep that in mind when making your final decision.

Makes sense. I think I'm leaning towards the 10.5" vs 9.5"; it really just boiled down to what works for AutoX and daily commuting before I can swap back to the OEM wheels. And if I needed to do anything like pulling pins to accommodate the 10.5", which I don't want to do, lol.

Apex order history isnt letting my view my orders from over a year ago but I'm 90% sure I ordered the wheels in the 10.5 fitment because it was a direct fit.

I have been bust lately and really haven't done any HPDEs this year but last year when I was active there were days that I'd through them on a few days before a trackday, I did some autocross events with them too.

Dont have any complaints with them.

Thanks for chiming in! What size tire were you running?

Car is in storage atm and I haven't driven it since July but I'm pretty sure I got 275s. Its definitely the hankook rs4s

Nice! I'm definitely leaning towards 275. Thanks so much for replying man.
