Wheels question

[onklp]

Hello guys i have question my 07 GP base model have 16 inch rims and i want to go to 17" but when i check rockauto it says my coilovers are just for 16 inch so thats means i need to change my struds in order to run bigger rims ?? And sorry for stupid question

No, you can run 17's no problem.

Lots of vehicles list parts that way. The struts on cars with 16', 17's and 18's on 2004-2008 cars are the same. (GXP's run different stuff).

Ok thank you

I'd look at 17 AND 18" wheels. 20" are available but the tire sidewalls get too short and you can bend a wheel by driving over the tiniest bump. If you are going bigger both work. Use a tire calculator to find an outside diameter that suits your requirements. Go to some custom wheel sites and you will find application guides that know what fits your vehicle for strut and wheel housing clearance.

20" are available but,

you'll break the transmission from the added unsprung weight. Most guys wouldn't run a 19" or above on the GM 4T65e because rebuilding it isn't fun.

~ fixed. :th_winking:

i am thinking to 17"or 18"

Go 18's, you'll regret 17's because they hardly look bigger than 16's.

Better tire choices with 18's too. You'll need 245/45/18 size tires.

But i was looking at my struts whit stock wheels and the cup where spring is sitting is very close to my tire so i'm thinking that 18's my not fit i feel like dummy now asking this question haha

Think about it.

You are lowering the tire sidewall height when you increase the rim size to keep the rolling diameter the exact same. Going from a 225/60 to a wider but lower sidewall 245/45 makes it all the same.

All this advice is right on! 18" wheels are the way to go!
