Cheap 18x10 +50 wheel for autox?

Besides how they look.... whats wrong with these for running 285/30/18 V710's on an FD on all 4 corners for autoxing?

A little background: I dont autox for points, or to be highly serious. Purely for fun. I dont go to every event, just when I feel like it. I am rather tired of being beat by nearly every car with race tires just because they have race tires. I am pretty consistantly one of the fastest on normal street tires.(as far as I can tell since its not like the standings mention what brand tire others are running ;) ) Given this, I figure I'm not going to learn a whole lot more running street tires, so I wouldnt mind spending a little bit of cash to get some sticky rubber. What I wont do is spend $1000+ for lightweight expensive 18x10's and then buy race rubber on top of it. Admittedly Id NEVER buy wheels like this for driving on the street. However, 1 event a month and 4-6 runs at each event I cant honestly justify paying high dollar for wheels.

Thoughts on these? Any experience with this brand? My only real worry is they weigh like 35lbs, or they are so weak they would bend from lateral loads exerted by 285 wide v710's....

Hard to beat the price, that is for sure. I really don't like the way that discount tire doesn't give the weights of the wheels or how they are made. At that price, I'm guess that is both gravity cast and heavy.

The Tire Rack has ASA JH8 18x9.5 ET45 wheels on closeout for $159. 23.8 lbs and low pressure cast. That may be more than you want to spend and it is a tad narrower, but it should (barely) fit according to the nifty Excel spreadsheet.

The only racing I've ever done is with running shoes, not tires so I haven't a clue.

Honestly, I think you'd be much better off getting some V710s in a 245/45 size on the stock wheels.

How come?

Does your opinion change if I have 370whp and 355ftlbs?

By the looks of them brake caliper clearance might be an issue, and they're probably really heavy, hurting performance.

theres a few guys runing these already .. dont know about that offset , is that the only offset they come in?

ya, considering how i work for that company, those are the most garbage wheels we offer. seriously, save your pennies and get some gram lights, or something light and wide.............................................. ......enkei rpf-1 anyone?

peace

Stock wheels are extremely light. That was my main factor in suggesting that.....what engine set up are you running? never know nowadays, could be a boosted inline 6 for all i know :lol:

I'd look for a decent used deal... call Fritz... or just stick with stockers. You'll get most of the benefit of R-compound rubber, even in 245, compared to street tires of a larger size. Won't be as much as w/ 285 race rubber, but you won't pay a terrible weight penalty (which also costs time, in both sheer weight, and deteriorated handling).

You could also consider 17x9's or 9.5's w/ 255/40's or 275/40's... that'll save you some money and the rim sizes aren't quite as rare.

Not to argue they might be garbage... but apparently you didnt read my first post where I said I will NOT spend big bucks for wheels I will use 6-8 times a year.... Gram lights are rather pricey to say the least...

Since you work there, what do they weigh?

uh, i have no idea, i would have to look when im at work, but i would say at least........................too much. dude, i have no idea, but EASILY twice as heavy as stock.

peace

i bet they weigh more like 45 or 50 lbs

Check out this thread too.

You can get a set of Rota Slipstreams in 17x8.5 and run a 255 size (all around) r-comp on them. They are around 15 lbs with a good offset:

Discount tire direct says 26lbs a piece. I just got off the phone with them.


I told them what wheel and the guy said "thats a great choice for your mustang" lol.

for $100 bucks a wheel they are hard to beat

9 +24
9 +35
10 +22
10 +50

this is probably your best bet right here.

I know this is not exactly accurate math, but from the slipstreams to those 18x10s you're looking at 11 more pounds per wheel, 44 more pounds total rotating weight. that's a BIG difference.

But also 30mm per side, so 60mm front, and 60mm rear. I would think that the 120mm more of race rubber would offset the 44lbs of unsprung weight? I dont know, thats just my guessing.

Any input into that?

weight is weight no matter how you cut it. unless you have the power to put down the weight issue, and the brakes to stop that weight from its path to destruction, it wont offset anything.
44 lbs is 44 lbs, thats half a backstreet boy.

peace

that's an odd question.

it's been said that one pound of unsprung weight is akin to adding anywhere from 2 - 10+ lbs of sprung weight to the vehicle, depending on who you are asking.

not quite! adding 44 lbs to unsprung weight would therefore "feel" like you are adding anywhere from 88 to 500+ lbs to a car.

in my experience, it's true. in 2003 (my stupid years) i had some extremely heavy axis 17x7 shit wheels on my 240sx that must have weighed 20+ lbs each. one day, i got a flat and had to use my oem 15x6. switching back to stock wheels made the car feel ridiculously nimble in comparison. seriously, i was shocked. i never put those axis wheels back on.

I agree with Rich... If money is a factor I would buy good tires (or slicks) for stock rims.

But also you should know that any good 285/30/18 tires will be well over the cost of those wheels... Some street tires in this size could be in the range of 300-350 a piece ($1200 a set). I recently bought a set of Bridgestone RE050A PP, 285/30/18s for my SSRs and it was as much as what I paid for the rims after I got them shipped and mounted.

Overall, I would listen to Rich and stick with stock rims (used set 300-400) and 245/45/16s (pending type of tires, $600-850/set).
And since you said you are not going to be competitive in autox, I would just put some cheap/reasonable performance tires on it and just have fun:) If you dial in your suspension and slicks, I bet you'll be pretty damn competitive!

Friend of mine here uses stock rims and 245s and did pretty well..

lightweight corners > wide tires

I've always heard the opposite, sacrifice weight for width within reason. Those who've tested this have found it to be true. 26lbs is not terrible for a cheap wheel that big. I'd still try to find something lighter though.

Within reason I suppose, 35lb/wheel is not.
