Tire rubbing on CS fenders with Moonbeam

OptionZero

Has CS officially stated how much wider their moonbeam kit is that stock

AntiVenom

no, they wont even tell you what offsets to buy until you are in the purchasing process. but i did some quick measurements before cutting. it is something like 1.25 front 1.5 rear.

edit: I measured the wheels backspacing and using a backspacing>offset converter I got -19.7mm of offset. I would say strasse nailed it. so the issue is 100% not with the wheel building process.
edit edit: will pop off the rear tires here shortly to measure them as well, but i expect to find no problems. mostly just checking off boxes to make sure i get the right measurements for this next round.

That drives me crazy. How can Carbon Signal not describe exactly how much wider their kit is than stock? Just relying on "their" specs seems ludicrous, because it winds up being your exact situation!

The only alternative is to get the fenders, install them, then use some stock wheels (or other generic wheels with known sizing), and then space them out with spacers until you get an approximate fitment, THEN order custom wheels. All of that is gonna take upwards to 8-12 months given how long it takes to order the fenders and custom wheels!

Stock body for me, at best i'd go something custom that i KNEW the specs for. Ridiculous they want whatever the **** they charge and can't tell you what the width of their fenders are, even approximately

AntiVenom

I hear you on all counts. The reality is you can stuff enough tire under a stock body.

To be fair, I never asked for the measurements, just their recommendation for offsets. Newb mistake I suppose. I just expected them to read what I wrote and if they weren't sure, tell me what their customers usually run, but with a caveat about it being aimed at X application (x being high camber and low profiles). I woulda just sucked it up and waited the extra 6-8 weeks after installing the kit. Live and learn I suppose.

I combed through the moonbeam threads for future reference. They are not keeping the width a secret.

Reading through the moonbeam threads, they mentioned something about the fenders especially designed for the moonbeam. I assume you have those?

Looks kind of tight with OEM wheels.

Ordered it all straight from them, so I assume so. I will double check with them. Wanna run a couple of other things past them anyway.

Invoice lists v2 fenders but they certainly don't look as spacious as that photo. Wonder what the specs on that wheel and tire are.

I'm pretty sure CarbonZ is sporting fly1 fenders... Notice how sharp the corner of the vent is on his fender and the CS are curved.
Here's a shot of their v2 fenders right off the CS website. The wheel looks like its behind the fender...

Doing some measuring across screen...much smaller diameter tire/but notice the radius of the backside of new fender vs the painted grey fender.
I know this is very hard to get exact from pic-but backside opening is at least .125" more.
wheels are definitely smaller...possibly a lower profile 18".
measurement's took across centerline,between door & wheel center on both,,,and then from rear fender edge & wheel center.
(pending steering wheel is in same position,,,more space/but not as much pictured because whel/tire is larger on grey car)

Hard to calculate with these pics....but tires are definitely closer to 24.75"dia. vs 26.75" on grey car...pending both are 19" wheels.

Based on the photo I'd say the car is running a 255-265 30 series tire.

As for offset my fronts are about the same specs but it's no wonder my rears are off if they went -26 on an 11. That retracts just over an inch from my 12" -25et. Which is about what I am estimating for a good fit.

I think the -20 fronts would work with a narrower tire especially with 2.5-3* No way the rears would work without something super extreme.

a cheaper, less invasive solution might just be to remove these tires and run something in the 255/30 range for clearance

while it may turn your stomach to run a "stretch", it'll be fine for DD

then get a second, cheaper set of wheels with better sizes for more rubber

something like 20x10 +0 in front and 20x11 -10 or something to fit 285 and 325 rears
