I am replacing my stock 17" wheels on my 04 ESV with stock 20" wheels from an 07 ESV. My questions are:
1). Do i need to be concerned about upgrading my brakes to deal with the larger wheel and increased weight issue?
2). What electronic eqmt may need to be recalibrated due to the wheel size change? (ie: Speedometer, etc)?
Any feedback is appreciated. Thanks

Your not going to notice much of a change. The tires on the 17" are HUGE while the tires on the 20's are pretty thin, almost equaling the size, not throwing off the speedometer by much (maybe 1 or 2mph). Theres crazy members on here with 24's and 26's with stock brakes and claim there isn't much of a difference from stock. The 20's wont be any difference at all, anything after 22" I think you should be concerned with brakes.

Just for shits and giggles, I measure my 17" tire and got 32" from across! wow..... I wonder what the 20's measure out to be....

I had 20s on mine, it felf the same, maybe even handled better. These 24s with stock brakes, it can get ugly. When speeding its hard to stop!

I am looking into better breaks. When these are hot and some ahole cuts you off, it can be an adventure!

I agree, just to be on the safe side. I dont drive the caddy much if I get an awesome deal on brakes, I'll definately upgrade.

07+ come with 18s or 22s. No stock 20 option. GM aftermarket, yes. Just an FYI....

http://www.miata.net/garage/tirecalc.html this sight is so great for matching tire sizes and speedo errors. The size difference (diamater) is nominal. Its the added weight that makes the braking difference, which will be minimal at best.

According to that site my stock tires 265 70 17's are 31.6" OD.... my new 09 22" factory rims i just picked up are 305 40 22 and ALSO 31.6" so my speedometer doesn't change :)

07+ 22s are the way to go IMO. ^^^^^^^^^^^^

I agree but isnt the offset different making the 22s stick out from the fenders, nothing looks worse than that IMO. I just bought a 03 ESV with 52K and I also want to go upgrade the wheels but with OEM, I was going to settle with the platinum 20s but if the 07 22s work than that would be great!!!

Thanks in advance

Platinum 20s from a pre 07 would be great too. All I can tell you is that lots of folks here have put 07+ 22s on their 02-06 Lades and they look incredible. Try a search, I remember seeing photos of several with 22s in threads a while back. And, they look even better on the 02-06 models than on the 07+ IMO. I have 18s on my 07, but would have gotten 20s if they were a factory option. The 22s were just not going to work for the regular snow I am in and did not want to have 2 sets of rims. I now regret not the getting 22s and then buying OEM 18s on ebay.

OEM GM, with pressure sensors, brand new toyo proxy ST's... for $1000

heres the catch, one of the rims has a 2 inch cracked lip, still holds air and was quoted $250 for the repair and re-chroming. So i basically spent $1250 for mint rims and brand new tires :)

Great deal! Like I said too, OEM 22s look even better on 02-06 than 07+ for some reason.
