Mind checking my math?

Hey guys, first post, but have been reading a good bit. Id like to post what i think will work and invite yall to let me know if i'm incorrect.
1986 Iroc
camaro tech states a 17x9.5 with a +10mm offeset front and rear will fit with a 275/40 tire.

id like to use a 17x9.5 rep c7 z06



wheel with a +54 offset. A 1.75-2" spacer should put the wheel back to the specified +10.

as of now running oe brakes front and rear, factory ride height. I intend to run zl1 brakes up front and 4th gen in the rear. Coilovers, and bmr a arms.
thoughts on this set up? Am i missing anything?

Glancing over it real quick it looks good. ....remember you can always adjust the adapter size that you buy a quarter inch here and there, it's when you don't have enough to begin with and wheels stick out! Yeah, 44 mm looks like 1.75" from what I can tell. I know coilovers have been known to cause some clearance issues here and there, and on our cars (speaking from reading, not experience) offer a negligible advantage if any at all, and can often cause problems.

ZL1 brakes probably require at least a 18" diameter wheel. I would dig in deeper on that topic if I were in your shoes.

i certainly will. Thanks for the feedback. Im not dead set on them, but a used set of brembo calipers for 400$ is really attractive compared to some house brand kits ive seen.

thanks for your response. I'll look more deeply into suspension options. Deff not an all out race car, but i do enjoy some more than spirited driving in the mountains.

I've got pretty much every stock style part, in tubular aftermarket from UMI, Ground Control weight jacks and Tokico shocks and struts. Stock 16" wheels and LS1 front disc brakes. While I don't RACE the car, I've had several people mention how impressed they were with how the car handled. Takeaway is that while I don't claim it to be able to set Nurburgring records, for spirited weekend driving it's WAY more than enough! -honestly if I were to do it again, I'd probably do shocks/struts/springs and brakes and call it a day. -and subframe connectors. That's kinda a given on these cars.
