20" rims
 

i have o7 gt with 18" rims now... thinking about getting 20's will all tires for this have low profile ? just curious about potholes etc around my area which are still bad.. if this would be a good idea to get 20's or not

I have 20's but bought taller tires than the "recommended" size. Sidewall isn't that much less than what I had on my stock 17's. Wheels are 20x9 with 245/40 and 20x10 with 295/35 Nitto Invo tires.

Here's how they look on the car:

Here's a shot of the front wheel:

I have 20's with 255/35/20's all around, They're Goodyear GTs, and feel no ride difference from my 18" stockers.

Personally, I don't like the look of the 20's with the low profile tires. Plus, I've heard more negatives than positives regarding performance and handling.

20" wheels = less traction. How can you keep up with the ls1, ls2, etc with heavy ass wheels that get no traction?

what tires would be good to get on 18x9.5 cs69 shelby rims instead of the 20" cs69 rims

EH? My 20's have a lot more traction then the stockers, they also increased handling a lot!

Those wheels look great on your car, also is that the new Techno hood?

I have 20" Foose rims with Nitto 555 tires. 255/35 front and 275/35 rear. Great handling combo!

Hood
 

The Dark Horse / Speedstar Saleen wheels look great! Saleen used the 20" wheels with great success I guess everyone has different feel for the road. My S-281 handles like it's on rails. What hood are you using and how much did it cost? Looks great! The GT brakes get lost though, in those rims. Time for a big brake kit to stop all that reciprocating mass!

my 06 handles great and looks great on 20's

Here are my low profile 20's and yes you feel the potholes more and have to slow down greatly for railroad tracks and speedbumps etc......I have 30 series all around and like War Machine 115 I am getting taller tires in the future when the BFGoodrichs are toast. I love the handling and stick to the 285/30/20's in back and the wide 265's up front but the tires in front are NOT even 27 inches tall:icon_doh:.....you live and learn but they do IMO look great and I have NO drop (yet):icon_wink:

see the small side wall in front (I have had no issues but am always careful and know the areas that I drive)

another couple of sharp cars with 20's !!

Reciprocating mass means moving parts like the engine...crank shaft,connecting rods and cams.Rotational mass is what your talking about..flywheels,wheels and tires.I got an explanation from my engineer daughter.

Put the same height and width tires on a 16" or 17" wheel, 20" would be heavier, rougher, and less traction

If you put the same height (35) and same width (255) your ride would be the same since the sidewall is the same, also if you have the same width your traction would be the same, plus you'd have way to thin of a tire for a mustang on that size rim, it would look silly and your speedo would be way off. Granted some 20's are heaver but the stock wheels are no light weights either.

If you wanted to get real technical since the radius is smaller the rate at which the circumference of the wheel would vector away from the tangent would be higher which would in turn of course be translated to the tire and due to the vector rate of a small wheel your contact patch would be ever so slightly smaller causing a reduction in traction, unless you ran a lower PSI to compensate for that, it's nothing that will really be noticed in the real world though(at least I don't imagine so) and that is WAY to much math for friday!

Ouch, my brain hurts now. 50 lash's with a wet noodle for you for all that real world math on a Friday......:)

I'll go with your daughter rotational mass works! 20's Rock!

LOL I know, that was about the extent of my brain power for the day :)

Just seems there has been a lot of 20's are no good threads around lately. My switch from 18" Stock polished bullets to my 20" Konig Beyonds (Incidentally I'm the car of the month on there web site. Woot!!) I gained a ton of handing, I'm sure it was wheels AND tires, and I don't feel I lost any power, but I did gain traction with my wider tires which sometimes feels like a power loss since I don't spin as easy.

Are you an idiot? I meant that the tires were the SAME width and height. Never said anything about aspect ratios and such. I mean measure the tire you put on your 20" with a tape measure and then find a 16" or 17" tire that is the same. You would have the same circumference and width but with more side wall.

I just went from the stock 18's to the 20" CS69's. 255/35/20 Nitto front, 285/30/20 Nitto Rear. Love them so far

I love my 20's They ride and look great. If you feel need the speed you just put on you race rims and M/T's

I'm saving up for a set of these 7 spoke 2281 Saleen series in black for my Grabber.

Sweet!!

by the way. Mine are as light as all the others. I just had to pay 3 times as much

So I was told
255/35-20 $126 x2 = $252
285/30-20 $259 x2 = $518

So $770....uuugh.....


Is that about right?

Ah and we resort to name calling, well I'm done with this thread because arguing over the internet is like winning the special olympics. Plus buy what you like and be happy.

Wow..someone always has to resort to name calling. Can't just have an intellectual debate or difference of opinion without some one always resorting to starting name calling and it looks like the instigator is you ...... What an idiot!!! :icon_angel:

Lampoon, yeah, that's about right. Nobody said 20's were cheap!

I just took off my 20's and am very happy I will never put another 20 on my car they looked good but sucked ass overall mine weiged in at 70 pounds a piece

CAN'T WE ALL JUST GET ALONG????

My 20's dont weigh much more than my Factory 18's. The UPS label on the 20's from American Muscle was 55 lbs each (including packaging). When I went to ship my 18's, they were 53 lbs each (including packaging).

Plus I run a set of 17" stockers front and back (with DR's in back) when I go to the track, so I was only worried about looks

i never called anyone an idiot...I simply asked a question...

I have the same size rear tires and they stick very well esp when warm.

In my case I just step on the gas and let the Whipple propel me forward at a heart pounding pace:icon_razz: But seriously there was such a huge difference in feel of the motor and the new found power even with 20's.... here is some proof

Yup you read right.....10.72 in the 1/4 mile with 20's:icon_steer:
You said you did not say that? :icon_shrug: Those are your words....right:icon_attention::icon_woot::icon_woo t:


Lets keep it as a debate and not take anything personally. Thats how threads get locked:icon_doh::icon_toast:

Just be careful.Interpretations get twisted in the context of a question or statement.I got pretty upset about a misunderstanding and got banned from the Grabber site,even my apology was misunderstood and I'm still banned.I still drive a grabber though. :)
