Would these wheels and tire setup be too stressful on stock suspension?
 

So I’m running stock wheels and suspension but I bought Rays Gram Lights 57DR 18x9.5 38+ 5x100 which are coming in soon and I plan on getting either Yokohama Advan Sports A/S 245/35R18 or Falken Azenis FK510 245/35ZR18 (leaning more toward the Falkens). I’m going for a flush fitment and I know I would need coils to achieve the best flush fitment. But I’ll handle the coils later I just wanna know would the wheels and tires be too heavy for the stock struts and such where it could potentially break something? Also would I experience going any slower in traffic with no performance mods besides a GrimmSpeed CAI? Would those tires even look good with the wheel size I bought? Im not going for the stretch look. If not what exact tire size should I get?

Also any advice and experience with Tein Flex Z (only considering for affordability) or BC BR Coils would be great! I’m not sure on the exact measurement I should drop the car with coils to get that perfect flush fitment without scrapping/rubbing. I’m thinking maybe 1.5” but not sure. Not sure about the camber measurements either. I don’t want to cheap out on anything so give it to me straight on what needs to be done for a good flush fitment. Should I get front and rear swift spring upgrade or leave standard - do I need to worry about spring rate - are rear extenders in the question? I know I’m asking a lot but I’m not looking to waste time and money.

The wheels and tires are unsprung weight. Do you have any camber in the front? I'm not sure, but those wheels may not clear the stock front struts with camber bolts.

Correct me if I’m wrong but don’t all cars come with a “natural” camber.. but to answer your question no. I haven’t touched the suspension or camber everything is stock. So would BC racing br coils fix them not clearing the front struts?

Coils should fix the potential clearance issue. That's a really common wheel/tire combo with coils.

These cars come with 0 camber on the front. When you start adding camber to the stock struts, you bring the top of the wheel closer to the spring perch.

There may be someone running these on stock suspension, and hopefully they chime in.

Would bringing the top of the wheel close to the spring perch be a bad thing? What exactly would that do

It's not a bad thing. You just need to be aware that with a 9.5" 38 offset wheel, you will be limited on camber with camber bolts. I ran 17x9 et 35 with -1.9 front camber. My wheel was about 3mm from the spring perch.

It's gonna look like a monster truck. You definitely need either lowering springs or camber bolts or new coilovers. Otherwise it's a pretty ugly look

ahh thanks for the heads up on that one now I’m reconsidering if I bought too big of a wheel lol it’s just I want that aggressive look without rolling my fenders.

yeah that’s what I’m hoping to avoid. if you have a flush fitment what setup are you running. drop a pic if you can

In this pic you can sort of see the fitment. I didn't do anything special, it's just 18x9.5 +45 with 255/35/18 tires and lowered 1.5" on coilovers.

First I have to say..BEAUTIFUL fucking build! Nice and subtle. And the fitment is pretty much exactly where I wanna be. Since your offset is +45 and the wheels I got are +38 it’s safe to say I’ll prob need to run spacers right? 15mm/20mm?

+38 offset pushes the wheel out more by 7mm over a +45. Spacers would just push it out even further.

Thanks! No idea about the spacers though.

makes sense idek what I was thinking haha so 5mm should be close to perfect right?

It'll be off by about 1/5 of an inch compared to the car you're using as an example. If you consider that close, then yes it'll be close to perfect.
