I troll everywhere

 

Any info on my post 3 up? lol.

 

You'll be fine with the 18s. Wes had them on his 2.4. Your speedo will be a lil off, but that's about it.

 

Word. It's just that I can get a set of gently used 18's with good tires for almost the same price as 4 new tires for mine. lol.

 

Yeah, they'll be fine. My SS/SC sees anything from 205/60/16s to 235/45/17s to the 215/45/18 stockers. They're all fine. The ride will be a LITTLE harsher but not too bad as long as you don't go with ultra low profile tires.

EDIT: Only thing is you'll need to be more concerned with potholes. I always leave my winters on until most of the potholes have been patched to help save the 18s.

 

Yeah, it'll be over summer anyway. I'm just deciding what I should do with the 17's. I'll probably keep them around for a little and decide how I like the 18's. The gunmetal will look great with the black... The drop will be first though probably.

 

Do you have winter tires yet? If not, I'd say keep the 17s for winter rims. You absolutely can't run the Rossos in the snow.

 

Nah. Just use my P6's 365. I replace 2 at a time and one of them is getting very thin, so I'm gonna at least have to drop 200 for 2 new ones... That's why I figured that for another 200 or so I could steal someones 18's... Plus, tires don't cost a whole lot more... I'd just stick with the P-Zeros probably...

 

You can't run the SS/SC stock tires in the snow. Hell you can't run them in the cold even. Anything below 35* and you get zero traction even on dry roads. If I were you I'd keep the 17s and buy cheap snow tires for them.

 

Yeah.. I'm stuck between getting the 18's with stock tires, or just getting some nice tires for mine.. some directionals and ****. We'll see. It's just that I'm trying to get some Recaros too, so I can't be throwing around that much money..

 

Not if you get the appropriately sized tires.

 

Yeah, but going from stock 2.4 size to stock 2.0 size will throw it off.

 

Exactly. The overall size of the wheels + tires has to be the same to keep it as is. If you use the same size tires for the 17's as you would for the 18's (height-wise), then add another inch to the wheels, it'd throw it off an inch.

 

or just update the tire size in the tune.

 

Yeah, mine are always off with my winter wheels. The tire size and diameter are almost dead on, but the tread depth is what throws it out of whack.

 

Technically you're off by pi (inches) for every revolution when adding a single inch in diameter to the wheel/tire combo.

I didn't realize you were going with stock SS/SC 18 inch wheels.

 

when i had my 2.2 with the 15s and jumped up to 17s mine was off but not enough to effect anything esp with the police running radareverwhere

 

I'm not even sure of the actual total diameter difference between the two sets... but it's going to be hardly noticable.

 

15s with 195 60s to 17 with 215 45s

it was about 5 or so off according to the speed signs

 

Yeah, it'll be like going 56.3 when the speedo reads 55. The speedo will read just under what you're actually going.

 

I encourage more of you to jump over to EcotecForum. Adam gave us our own private section there.

 

does it get whored up over there?

 

This calculator will help you to see what the different sizes will do. Play with it and get something you are comfortable with

Yeah. I talked to my dad and I'm probably just gonna get the factory s/c 18's with the P-Zeros from someone on here as a take-off, then keep the 17's for winter since the P6's are reasonable in the snow. So resetting the wheel size to 18 probably wouldn't help me unless I could tweak it to like 17.5? lol. Maybe you could set it to 17 with beefier tires to put it somewhere in-between?

In the Pittsburgh area, whos the guy to go to for one of these ECU tunes I've heard so much about? How much?
