I understand this isnt a REAL FI question, but it sorta is and i need urgent help.

About a week ago I purchased a set of Konig Reasons from tires.com super cheap 16 inch wrapped in BFgoodrich kd's. They said they would be here in 1 week. They arent. I just walked out side and some a$$hole or someone messed with my tires cuz there is no way that my 2 fronts just decided to go flat all at the same time. I tried filling them and they dont hold air long. Of course I only have 1 donut so thats not an option.

I called tires.com it turns out my rims are in the middle of the ocean right now on their way over. Storm difficulties set the order back (Sounds like what happened with my C2 order.) Everytime i purchase something overseas it gets stuckin the middle of the ocean. Anyways, they are letting me change out my order if i want, very generous of them.

Here is why i put the question under FI, They dont have any 16's in any of the setups that I like, only 17 and 18. Of course im not going to go 18 with my new C2 setup, It would be a waste of good power. But how much will it effect the performance if i put on 17's. Is there that much difference with a turbo'd celi between 16s and 17s. I know when i switched from stock 15s to 16 GTS rims i stopped chirping in 2nd gear. What would you do?

They can ship them to my house by the weekend if I switch my order to the Konig trouble 17's.

Thanks in advance

Only reason i'm scared is because i went to the track with Jay who has the DA sports kit and he ran low 15's all night with konig prohets 18 inch. Then we went 2 weeks later and he had switched to his stocks on teh front and hit 14.4-5. He also changed his exhaust out. So im not sure how i feel about this. It would be a shame to be running turbo and not be consisten low to mid 14s at least. Afterall, i did spend over 3k on this.

Hey watch it.. first... its the DA kit.. what more do you want.. his fuel tuning is with a little black box. And.. where are all the GT-T's with 13's. I have yet to see one yet. I only see GTS's in the 13's and they are only running 186 whp.

I wouldnt know that since no one has posted a time slip or put their time on the board with under 14 on a GT, except the 3sgte, which isnt really a GT, and the vvtli GT which again is not a GT.

Crap.. hes making me buy their wheel kit, the 5 lugs per wheel at 45.00. Do i need these if i have the ones that came with the GTS rims. Are they universal?? Am i getting a bad deal here, i feel like im getting butt****ed.

17's are not going to be as bad as 18's, i believe the rotational intertia of a ring (which a rim isnt exactly, almost a cross between a disk and a ring) is 1/2 mr^2. A solid disk is just mr^2, So i guess the rotational intertia of a rim would be somewhere inbetween the two, depends on the design, But reguardless...

But if i get a lower profile tire than it would be almost like having 16's with the 17's.. correct?


What to take from the equation? Its going to get harder to turn the wheel as you add length to the radius... more so then adding mass, because radius is squared. People seem to make a bigger deal about getting light weight rims then getting smaller rims, should be the other way around.

****, so go with 205/50/16? or 215/40/17.
And would BFGoodritch G/force sport be ok for a turbo'd car on street?
