Civic Type R After-market Wheel Guide

[Kami Speed]

Seems the Acura NSX y spoke forged wheel will be the autocross wheel of choice 19x8.5 +55

And it's light! but expensive..

you guys seen them mounted on a FK8 yet? I'd love to see some pictures

Think you could share more angles?

any reason why you went with 255/35/18s over 255/40s?
is the offset too aggressive to run a 255/40 series tire? I like those wheels but I prefer to run a 255/40 or a 265/35 series to keep similiar diameter as stock.
Wonder if the 45 series they plan on making will allow me to do that.

I actually ran a 265/35 achillies atr k sport tire on stock suspension without rubbing while Jonny ran a 255/35 RE71 lowered on Eibach springs. Titan7 reccomends a max of 255 on the +35 offset. They will have a +45 offset that will be more suited for 265. Never thought of doing a 40 instead but looking at the gap left when lowered on 255 it may rub.

oh oops, i must've read the sidewall wrong lol. Looked like it said 255/35.

Thanks for the info. Still debating btwn a 35 or a 45 offset..

Just got these's put on for the winter time
18x8 sport edtion A13 Mt Titan with 235/45R-18 kumho solus came out to under 900 from tire rack
I think they look decent for a winter setup. Cant wait for my te37s next year

Only photos I have without tires unfortunately but you can fit a 265-245 tire recommended reverse stagger for autocross and a rear bar for Stock Class cars

Hey, I recognize those photos!

Lower sidewalk you gain a gearing advantage more MPH in gear. When in doubt go down and out. Down in diameter size, out with section width. Example I have a 245/35/20 re71r on my CTR lost like 2 or 3mph in second gear. So instead of 63mph it's 60mph

Got my new winter shoes. Pretty happy with how they look. About to go test them out.

Hi all, does anyone know what the original scrub radius is on our cars? Debating whether +40 offset on a 18x8.5 would cause too much torque steer, kickback, all that good stuff...
I saw the posts by baldheadracer and that he's not happy with the +45, but still would like to know how much I'm adding to the scrub radius with a +40 offset, i.e. what is the original scr. radius.
Thank you all.

I'm not able to give you an accurate measurement in terms of number but Honda released a diagram where they discuss the differences between the base and the CTR. you can see the steering axis or king pin line comes very very close to the centerline is (zer0) that's is where you have zero scrub. Absolute zero scrub radius is "bad" it creates squirm. But assuming you do your math of 8.5in width with an et60 you can find the centerline of your rim which will also line with the center of the tire (obvious I know but still) I believe the CTR is near zero toward the negative side. Idk I'm no engineer but basically you want the hub offset to remain similar to the width of the oem wheel as a ratio. Like. I believe 9.5 with +47 is absolutely perfect but don't quote it. So 9.5 on a 45 should be good. I have ordered a set of Ce28SL 18x9.5 +44 when I get the road ready next season I can update if you wanna wait that long. If not. Pull out a ruler and start measuring. There should be an obvious pivot point on the tire if you record a rotation of it. I'm sure there is a video on YouTube about the CTR and its scrub radius. Hope that helped I know it was lengthy

Thank you Anthony, quite helpful.
I ordered the Alleggerita HLT 18x8.5 ET40, with 235/45/18 Pirelli all seasons; thought 40 would be ok, and didn't see better options in my price range on Tire Rack, don't wanna deal with other vendors. Now I'm having second thoughts, though Tire Rack and my mechanic who's an enthusiast and friend assure me I'll be ok...
