Hey all

im going to be getting some 20" rims for my eldo and do a 2 inch drop all around and i wanted to know if anyone had any experience with 20" rims and what i can expect in performance ride control,m comfort and so on.

It is going to feel like a huge difference when you first start driving. When I put mine on, it felt real uncomfortable but now I love the way they feel. Whenever I put my stocks back on for whatever reason, i dont like the way the stocks feel. I guess each time I switch em I just gotta get use to the new feeling again.
Positives: I like the way the ride is better with the low pros; they look better IMO; a whole lot more attention (I like it or else I wouldn't have put spinners on); you get to pull up to trucks on 20s and laugh cuz you have 20s on your car
Negatives: POT HOLES, I got 245/35/20 Nittos and I live in the City, Pot holes all over the place; don't know where you live, but gotta worry about getting them stolen

Also, I know when I have my stocks on and I step hard on the gas from a stop, my tires chirp; w/ the 20s it never happens, not sure if that is good or bad but just some more information from my experiences. I didn't drop mine at all so only speaking from what I know...I saw an Eldo on 20s in my area, looked real clean

cool, well the reason for your 20s not chirping because of the mechanical disadvantage they have,(thats why its a good idea for a bigger brake setup;) ) lts just harder to turn a larger wheel and plus you have more traction. and i dont think they would get stolen around my area and there arent too many potholes.

thanks for the info. no pot holes and not worried about getting em stolen= what are you waiting for? do it, i have no regrets... good luck, post some pics when you do it, i got a bunch of pics but been lazy on using someone's scanner...

well i would except the mula isnt really flowing too well right now (unemployed)

but these are the wheels im thinking of

and they will be going on here

and yes.....im 17:)

I just stuck 20" 150 spokes on my '82 Coupe Deville and I am still running around with a boner. Looks freaking awesome.

is there any way to fit a 40 profile on the 20s ?? whats the bigest ?

Your right its a mechanical disadvantage... Even if your tire/wheel package swap weighs the same or even less, the weight is farther out from the center of the rim... Which means more inertia, and when you accelerate you get a negative corolis affect, which is really what kills the acceleration... Something on the order of ~15 hp..

So drop in a big brake kit and a K&N cold air intake.

20's on a car - especially a luxury sedan like a Cadillac - is about one thing: THE LOOK. You should only do it if you love and have to have that look because the look is the only positive. The negatives are considerable:
1) Expense (and alot of it - especially when they bend due to normal driving including expansion strips and potholes)
2) Reduced performance. Acceleration diminishes, braking increases, fuel mileage decreases. All this is to the usually considerably higher unsprung weight (a performance-killer) plus the aforementioned inertia issues.
3) Safety issues. Besides losing performance as-noted above - handling can diminish due to the weight. Plus, the offset is frequently different from factory specs which can have a significant impact on handling dynamics.

I'll get off my soap-box now. I'm an enthusiast as well and I remember well my diehard days. If you want them bad-enough - get them. Just keep the above in the back of your mind. That all said - if/when my ship comes back in - look for me in a Black/Black DTS on chrome 19's. ;)

have fun - be safe.

forgetfullnei used to have 16" rims on vouges on my 92 deville, ride was perfect

now ive ben having 20'z since last sept. 150 spoke. sumtimes i regret that i did not go bigger...then i go back an think, if i went bigger, it be hard as hell to drive it, the way I drive.

the whole acceleration thing doesnt seem to bother me, i guess my LT handles it fine.:burn:

u will be able to "feel" bumbs an shiet like that more threw the car. personally i love the way it drives, except when there are pot holes, then u really feel the weight of the rim. ( have two dents as we speak)
also, u can feel the waves in pavement....and u need to make sure u have the 20'z balanced, an pressure is correct, because if ur not up on it, u could have a irratic feeling ride.

I am going to do a little drop all the way round too, bout 2"
- the only thing that disapointed me, was i was gettin pereli tires, but since the back skirt had a narrow opening i could only fit some Hankook tires, width= 245

on ur car, i wouldnt go bigger then 20'z
if u want best ride....id prolly go with 18'z & vouges, i think it would look tight on a el dog (or u could go with 19'z an vouges, but the bigger vouges only have a yellow stripe, unless u gettin truck vouges)
or u could just snap and get 22'z
u might as well tint ur windows all the way around too, cuz u'll have ppl "lookin" @ u
...p.s....u have protection?:gungrin: i dont know where u live....

and the whole spinner deal....if ur not gettin spreeZ dont bother, all the ad-on spinners look too cheap, might as well get them spinning hubcaps:vomit:

only my personal opinion

...ohh i almost forgot

i had to change my whole brake setup, because the rims depleted my brakes SOOOO quick
now i have perfomance rotors, and perfomance pads in front, was supposed to get slotted rotors, but didnt want to wait for them, since i waited a week anyway
and in the back, i wanted to do a drum-disk swap, but hey...thats $$$$ so i just got heavy duty towing drums+ sum synthetick semi-metalic shoes
brakin is perfect now ($500.00 later)
u should check all ur ball joints, an all that front end

Just saw this post came back up. they arent sprewells (Davins) but not just an attachment. The spinner only goes with this rim, not like the spintek and chopper attachments that go on anything. Sold the caddy, too many problems with it, rims are for sale now, anybody want them email me... nthn2aboss@yahoo.com. Omega Zab Judah II 20 Inch Spinners

And for the whole spoke deal... if they aren't Daytons don't bother, the 1500 dollar 22s with tires will bend super easy. Unless they have the Dayton emblem on em they are just another set of spokes. Might as well just throw the hubcap spokes on it. anybody can throw cheap spokes on something... :vomit:
Only my personal opinion, spokes belong on old schools... :bling:

is there any way to fit a 40 profile on the 20s ?? whats the bigest ?

All of the places I've talked too said no way to 40's on 19's & 20's. I don't even think 40's would work with 18's but I'm not sure.

I've been trying to find someone with experience using 18''+ with the Tire Pressure Monitoring System ( TPMS ). Vouge only supports 17'' and maybee now they do 18'' with their Alias wheel. My DHS has the stock 16'' setup and it doesn't make sense to do just a plus one with the 17''.

If I can keep my TPMS with 18'' I might do that otherwise I'll turn it off and do 19's or 20's.

with 20s ure gonna run thorugh tires quicker, you have to avoid potholes. You acceltarion will slow, braking will lag a little, unless u upgrade, the handling will improve due to the wider tire and stiffer sidwalls, and ure gas mileage goes down somwhat also. Plus there is a definite ride difference on low pros.

i just wanted to know they want you to run a 35 on a 20 what is the biggest i can go cuz if i can get a 40 on it i will get me some 20 s

This guy has 22" rims with i think 30s, he says he didnt do anything to his suspension and he does not rub, i think 40s should be fine if these extra 2 inches of rim are fine... just speakin off what I would guess with my common sense, don't quote me, i dont really no shit about cars except how to make em look clean

In response to several replies I agree that spokes belong on the old-school Cadillacs. I'm really interested in getting some 20's on my car.

1.Would 20(spokes of course) look right on my Caddy? Check my link to view pics.
2.Also would I have to re-do my whole brakes as well?

And I think I need to lift my back-end up a bit, so I'm thinking about getting air-shocks, I just hope it doesn't interfere with my automatic leveling.

Thanks for any/all feedback

you missed the fact that he has 265mm width tires on his car.

No I didn't. Just using my common sense which was wrong I guess, still don't know what that width has to do with the height though. But like I said, I dont really know anything about that. THanks for correcting me though.

Ive seen 20" spokes on a caddy like that before, i thought it looked real clean.

i think 22" billet style rims would look tight

u will most likely have to upgrade ur brakes

and about the rear lift, u can most likely get heavy duty towing shocks in the back that will connect to ur lines, and just geta adaptor for the levelor, or you could just get adjustable shocks, so u can adjust the height ur self

whats up all, I have a 91 Cadillac Brougham that I want upgrade wheel size on but I'm not sure what's the biggest I should go with and not have to worry about having problems with suspension and handling. The stock rims are 16 inch. I am also worried about any problems I may have with the auto level ride system if I go with bigger rims??? Anyone have any info. I would appreciate it. Dayton spokes are the rims I am going to get but I just need to know the max size to go with. Thanks

sidewall number is proportional to width of the tire

From what I've read a larger rim say......going from a 17 or 18 to a 20 or 22 will actually slow you from 0 because it is harder to get the bigger rim rotating. You must upgrade brakes also because it is also harder to stop rotating.

GO WITH 17'Z OR 18'Z THEN, IF U DONT WANT TO UPGRADE ANYTHING ELSE

AND DONT WORRY ABOUT THE AUTO LEVEL SO MUCH

Check out some of these rims for your ride>

I run a 245-40-ZR20 Falken tire (27.71 dia) on my 98 STS and have no problems with rubbing at full lock to lock. I would have liked to go wider with such a tall tire, but I'll take the lack of rubbing over the look of wide rubber any day.

Kingsize

well i went to pep boys and did alot of comparing in tire size

this is what i came up with

an 18" wheel with 245/40/18 tire are the same (or damn close) to my 225/60/16 stockers.

so all i have to do if find the right offset and then maybe get an appropiate spacer or get the rim machined to fit jsut right and BAM its fits like a dream also im getting a 2" drop all around so i'll have to get an alignmet too
