Default 205/50/15 ANY ADVANTAGE to running this on a 15x7 vs. a 15x6.5?

everyone seems to run this size tire. heliums are light and cheap, but only 6.5" wide. i could get the slipstreams in 15x7 and pickup some width but also some weight. i gave up on the 16x7 slipstream idea since they have 15x7. i thought they only had 15x6.5. blablabla. blaaaahhh. any thoughts? opinions? suggestions? these wheels will be used for autox only(maybe an hpde, if i can ever put the money together with the date.

Of course there's always an advantage of running wider wheels. Your tires will have a bigger contact patch. I say spend the extra money and get the extra 1/2". Do it right the first time.

Most 205/50/15 tires I have noticed a big difference from moving from a 6.5" wheel to 7" wide. Contact patch and also sidewall isn't able to roll as much.

for most people the extra 1/2" of width more than makes up for extra couple of pounds of weight.

Since i have become the poster child for busting Rota's on an auto cross course i would warn agaist them for road racing.. At least with an auto x you can check the wheel after each run... go to goodwin racing .com for cheep wheels.

You're only talking about a difference of half an inch, which is tiny. Don't worry about it. Get the 15x6.5 if you really want to get those wheels.

No, they won't. They may have a wider contact patch, but its size (area) will be the same. The area of the contact patch depends only on the weight of the car and the inflation of the tires, not on the width or size of the wheels or tires. For example, if you inflate the tires in a 2640-pound Integra Type R to 33 pounds per square inch, the area of the contact patches will total 80 square inches, regardless of whether the tires are skinny 185's or steamroller 245's, and regardless of whether the wheels are 15x5 or 15x8.

Which Rotas are those? The lug area looks different from my C8s, more like Konig Heliums.

It's the shape of the contact patch that's important...a wider wheel makes the shape 'better' for taking corners.

If you autox and every tenth of a second is important, then a wider wheel (not too wide, there is a point of no return) is a faster wheel.

yeah the lug area definitely looks different from both of my sets of c8's. However, one of my C8 wheels did crack like that, but Rota had a new one at my door within 10 biz days, no questions asked, no expenses to me.

Heliums, and i was promised a replacement but now 9 months later and a pile of excuses i still have not seen it.. I was even forced to ship back the broken one at my expense. Then i got an email letting me know that they would take care of it and a new one would be shipped out and still nothing... So i would not recommend them and Konig for any thing except for plant holders..

Yes get the 15x7" and get these. Scroll down to the Hanabi - 11lbs and only $89. Awesome price for that wheel. I've picked up a set for autox and no problems so far.

I wish you replied to my thread a while back about 17x7.5 vs 17x8 on the RSX. I was persuaded to settle for 17x7.5 (though the 17x8 is a +3month wait, if they CAN even import them since the wheel is discontinued so getting the 17x8 wasn't even a guarantee even if I wait). Guess I am stuck with 225/45.</TD></TR></TABLE>

A 225/45/17 is pretty good on a 7.5" wheel, but would definitely be nice on an 8" wheel. But in all honesty, if you aren't out for the last tenth of a second, the 7.5" will work just fine.

That is a sick price... I may have to pick up a set of those. Anybody interested in a set of 15x7" Slips in bronze?

That's what I was going to ask... Heliums are Konig, not Rotas. And what is it about edgeracing cheap wheels that make them better than Rotas, except for their re-badged Pro-Race wheels? Based on past posts here from other people's experiences, Rota would have given you a replacement a long time ago.

AND, I would love to see the actual weight of the Falken Hanabis on a good scale.

No, they're Konig Heliums, which are notorious for cracking spokes under autocross and track conditions. Konig is also notorious for not supporting their product by offering replacements for cracked wheels.

The Rota Slipstream has proven to be far more durable. I've seen a few Rota models (notably the Circuit 8 and the Attack) crack or break in a competition environment, but I have yet to see a broken Slipstream - and there are countless Slips being used on autocross and track cars out there. In addition, every broken Rota I've heard of has been replaced by Rota.

no you need to. You didn't deystroy a set of rota's, you did that to a set of konig helums, which have been known, since shortly after they came out, to be very week.

I think the only reason Slipstreams draw any criticism is because they are a blatant look-copy of the vaunted Spoon high strength, low weight wheels that used to be produced by the Desmond factory in Russia.

Sure, compared to the Spoon wheels you're going to see more broken Slipstreams, but you're talking maybe $450 vs $1600.

Most of us would take our chances.

And just so you know, most of us who have been driving these things for six or seven years...well, most of us have witnessed at least one broken Desmond-made wheel by now. Nothing's impervious to abuse.

Gotta tell ya a funny story. The HT user "mstewar" bought a used racing DC2 ITR that came with spare sets of wheels. He sold me a set of SSR Type C 15x7 +38 for $400.

I had no idea.

I thought I was buying some kind of Kosei equivalent, and only noticed how light they were when I went to put tyres on them. After I'd used them for a couple of years and decided that they were working out pretty well, I tried to find another set somewhere.

Cheapest I could find was $1200.

I had no bloody idea I had such a good deal!!
