Sadly the calculator doesn't have an option with coilovers for calculations but that might be because coilovers might have different clearances depending on the brand(never know). I'd say a good 7-10mm distance from +38 is the maximum. Although someone was able to fit an 18x9.5 +50 on coilovers but he was also running huge stretch with 225 wheels and -2 camber. http://www.ft86club.com/forums/showthread.php?t=63769

Thanks! I've seen +44/45 too, but didn't know that +38 was for clearance reasons. I thought +38 was to push it out a bit to get a 'flush' look. So coils giving +7 sounds reasonable. The post you linked on +50 seems to mention some spacers to make it functionally +30, so that's probably why the need for huge cambers.

On a 9.5 wheel, +38 is the limit with camber and an inch drop because it pushes the wheel out where it mounts. A great example of this is people running 18x9.5 Gram Light 57CR's with 245/35/18 tires while dropped an inch. The clearance is about or less than 3mm on stock suspension (with lowering springs).

Due to the decrease in spring perch diameter when making the move to coilovers, it opens vast options for wheel choices and aggressive wheel setups since 9.5 seems to be the go-to for a lot of people.

I'm still on stock suspension as of now but will eventually make the move to coilovers and 9.5 wide wheels. Playing around with the calculator really helps me by using stock suspension as a reference. The popular 18x9.5 wide wheel will comfortably fit coilovers at +45 offset using the calculator and giving yourself about a 7-10mm buffer. Glad to help fellow 86 driver!

Thanks again for your help. With those specs, the online calculator is still showing a 'flush distance' of +17mm. Is it just overestimating the poke?

To get it to 0mm, camber has to be adjusted to -3.1. I don't think that many people are really running such aggressive cambers?

EDIT: I'm actually tempted to push it a bit further to 18x10 +40...
a few reports here
staggered offset and tyre width, lowered quite a bit

@dominicpadawan looks like you just updated the calculator with coilovers clearance if a value is picked for the coilover! Cool!

Just wondering if you have a place where you publish updates and changelogs?

Hi, the updates are published in this thread on previous pages. But I don't plan to release other updates because the calculator seems to be complete, it's been a while since nobody asked for modifications.

Thank you

Howdy, I really appreciate this tool for the community. Is the source code available anywhere? I'd like to re-host this on my personal website as a mirror. I'm going to start working on rehosting a lot of valuable 86 related tools and information as I'm concerned about the long-term availability of the FT86Club Forums and other's personal sites.

Hi Tristor,

The source code is not available, this tool is exclusive to FT86motorsports.com. However, you can put a link on your website. Thank you.

If I don't want to roll the fenders or attach a wide body kit, do I need to keep the Flush Distance as a negative number? If so, I don't understand how 18x9.5s, or even 17x9s fit on this car without rubbing. The negative camber helps but even with 3 degrees the calculator has +7mm flush distance. What's the maximum flush distance before it rubs when the tire moves up?

Where abouts is the "flush distance" being measure from

The top of the rim to the vertical line of where the fender stops?

The centre of the rim to the vertical line of where the fender stops?

or the bottom of the rim to the vertical line of where the fender stops?

Cheers

you see that 90 degree angle bracket coming off the upper fender.. pretty sure that's where the site is measureing flush at

Hi,

Flush distance is the side of the rim beeing flush with the side of the fender. To be flush, the side of the rim have to be aligned with the vertical line.

Thanks.
