Spoon Sports - Progressive Springs for FK8

[typearghhhh]

I'm running Michelin PS4S tires. I'm fairly certain I'm going to need some modification but I'm hoping I can get away with minimal cutting.

i rub on stock height without springs on 18 x 9.5 38 offset on 265 as4's but only on dips

That's weird. I don't rub at all no matter how much suspension flex

Yeah it looks like the Michelin AS4's run pretty wide - at least compared to the Firehawk Indy 500's which people on this forum have reported don't rub at 265/35, +38 offset, and lowered. Based on Tirerack specs, the AS4 seems to run .2" larger than the Indy 500 in both section width and overall diameter with the same size. Tread width is around .7" narrower with the Indy 500's as well so that might play a role in being narrower at the edges of the tire itself? I wouldn't be surprised if that difference accounted for the rub/no rub.

Not sure what other tires people are successfully running at this size and offset, but based on what I've read on the forum the Indy 500 seems to be a good rule of thumb to compare against.

Michelin PSAS4 - 265/35/18

Firestone Firehawk Indy 500 - 265/35/18

Small rub on sidemarker tab on dips at speed. If I bend the tab I reckon it’ll be gone. No rubbing in the back. No camber arms in the back. Also pulled the front camber bolts.

I haven’t done an alignment yet so I don’t have the settings.

Have you gotten an alignment yet? I'm thinking about getting the same setup as you and I'm wondering if it helped with the rubbing.

Not yet. Got in an accident a few weeks ago. I’ll post an update if/when I get an alignment done

Damn, hope you and your car are doing ok!

Just got my Spoon springs installed today. I noticed the rear is a bit lower than the front and wonder if it's just the cut of the fenders or has anyone experienced settling?

Anyone running these with 18x9.5 +38 with 265/35 RT615K+? Stock camber rear but have pulled pins up front and will also be doing front lower camber joints, hoping to end up around -3.5 up front. Maybe I can get away with just bending the front tab?

You will be able to use that setup without a front lower camber joints. Just gotta bend the front tabs
