Yeah I saw the pics - totally nuts. How did you get into ice racing?

Did you do rally first? I'm interested how you got from your first racing experience to ice racing. Feel free to point me to a search or post if you alreayd explaine it to someone else : )

I just edited my post to add some clarification. - Toy_Guy 2002-11-16 06:04:34 (825 views)

you know what's funny - frank 2002-11-15 16:52:31 (1071 views)

The only variable with a wheel is the weight (within a given size) - this is not the case with tires - Mirror|rorriM 2002-11-15 22:20:29 (991 views)

Actually - squidix9 2002-11-16 21:43:13 (1558 views)

Those look mean ; ) - Singletrack 2002-11-17 16:25:40 (801 views)

That's a cool site, couldn't find the video though. - Singletrack 2002-11-18 07:17:19 (637 views)

I got into ice racing because - squidix9 2002-11-19 13:18:56 (726 views)

Very cool man, thanks for all the info : ) - Singletrack 2002-11-19 14:35:36 (489 views)

Other than being F*&^&!g cold winter is cool for racing - squidix9 2002-11-19 20:12:02 (542 views)

I looked into this. Toyo TS-1 is the lightest in a given size. Bridgestone S0-3 is real heavy. - PhoenixS4 2002-11-15 17:08:59 (1678 views)

And don;t forget, a 235 is about a pound heavier than a 225. - PhoenixS4 2002-11-15 17:39:23 (615 views)

but - BSOD 2002-11-15 17:07:09 (652 views)

Good point. I speced out my winter vs summer weight about a month ago and - Singletrack 2002-11-15 17:00:48 (778 views)

werd, and tires are cheaper than bling bling rims - frank 2002-11-15 17:02:27 (1234 views)

unless you're sensible... OZ SL's are light and well priced. - S4 from GT 2002-11-16 01:22:13 (928 views)

A little flawed on rotational inertia. You have to chop the wheel in a thin pizza slice... - Audiboy 2002-11-15 15:24:12 (1243 views)

I think that's what the modern world calls 'Calculus' ;-) - Mirror|rorriM 2002-11-15 22:16:30 (690 views)

woah...old man of the internet...aim# 9!?! and I though I;d been here a while - SwampGTI 2002-11-15 17:04:20 (698 views)

oops, nevermind, I just read George reply. - Audiboy 2002-11-15 15:26:39 (665 views)

Nice analysis ... - sj6spslvrS4sdn 2002-11-15 15:12:22 (635 views)

Sounds about right to me. I have always gone by 1lb unsprung equals around 3 times sprung. - Singletrack 2002-11-15 14:08:09 (605 views)

Is this in Engrish? - Ben AKA NUHuskyfan 2002-11-15 14:02:20 (575 views)

Don't forget the Moment of Inertia for the Brake rotors, etc... ;) - reefer_bob 2002-11-15 13:58:37 (793 views)

I think saving 16 lbs. on brake rotors felt like it saved me 19.2 lbs. based on this... - LCP 2002-11-15 15:34:14 (716 views)

What size is the OZ forged wheel and what does it look like? - PhoenixS4 2002-11-15 14:08:55 (1076 views)

I've got a bunch of 15X7's and 15X8's - squidix9 2002-11-15 21:23:46 (972 views)

The analysis is valid for no loss of traction. A burnout has different dynamics. - Toy_Guy 2002-11-15 13:59:20 (563 views)

True, but my point is the ability to - squidix9 2002-11-15 21:19:23 (624 views)

OK!!! All fixed up with the sub/superscripts added in. - Toy_Guy 2002-11-15 13:44:17 (735 views)

You're a swell guy. =) - LCP 2002-11-15 15:21:38 (617 views)

I would stress in the beginning its a 10 lb reduction PER wheel/tire just to clarify - Stealth4 2002-11-15 13:34:39 (614 views)

So ultralight tires is where the smart money's at!! - RichmondS4 2002-11-15 13:28:41 (765 views)

so my effective weight loss, if i bought lighter wheels, doesn't justify my effective wallet burn. - Mr. Piggie(mike01s4) 2002-11-15 13:12:22 (810 views)

...and that's why manufacturers don't do it either... - LCP 2002-11-15 13:14:57 (821 views)

No - making the wheels *heavier* can aid fuel economy - Mirror|rorriM 2002-11-15 14:10:04 (761 views)

I think that's a stretch - stiles_s 2002-11-15 14:48:35 (639 views)

I know it's a stretch...it really depends on what the EPA uses for their test - Mirror|rorriM 2002-11-15 15:02:10 (557 views)

for mfg'ers, cost of a heavy/stong wheel << cost of a light/strong wheel - BSOD 2002-11-15 13:45:48 (719 views)

why dont you do it :) - Stealth4 2002-11-15 13:15:25 (679 views)

Toy Guy did enough as it is! - Mr. Piggie(mike01s4) 2002-11-15 13:09:43 (630 views)

Thats close, but not quite right... - George @ BostonAudi 2002-11-15 12:55:16 (1002 views)

By pretending the mass was all at the radius of the wheel/tire, he gave the best case scenario - Mirror|rorriM 2002-11-15 14:05:19 (667 views)

Exactly, Jeff. I'm glad you follow the simple physics! - Toy_Guy 2002-11-15 14:15:39 (534 views)

I think the internet tuning business would die if we started scanning the books on our shelves :-) - Mirror|rorriM 2002-11-15 14:17:38 (531 views)

George, why don't you try reading my post in entirety before commenting? - Toy_Guy 2002-11-15 13:45:37 (622 views)

I read the entire post. Twice now... - George @ BostonAudi 2002-11-15 13:59:03 (724 views)

It's sound. - Mirror|rorriM 2002-11-15 14:16:11 (711 views)

Agree. I was thinking of acceleration and braking, not constant velocity when I posted above. - Audiboy 2002-11-15 15:33:13 (576 views)

The same math applies, regardless of acceleration - Mirror|rorriM 2002-11-15 22:22:48 (547 views)

Well, I'll back out in disagreement... - George @ BostonAudi 2002-11-15 14:29:56 (637 views)

Sorry, my terminology was misleading - Mirror|rorriM 2002-11-15 14:40:29 (600 views)

"how the car is driven" == AWD vs 2WD, not driver skill :) - George @ BostonAudi 2002-11-15 14:00:59 (1019 views)

That only affects dyno numbers, not the actual #s put down on the pavement - Mirror|rorriM 2002-11-15 14:11:18 (596 views)

george, he's calculating it as if all the weight was all the way - BiTurboBoy 2002-11-15 13:02:39 (763 views)

Right... I've always seen approx 4x equivalence... - George @ BostonAudi 2002-11-15 13:04:43 (773 views)

damn, engineering is hard to read without subscripts.... - BiTurboBoy 2002-11-15 12:45:02 (679 views)

You could be totally wrong and I would have no clue, but it sounds good =) - 2k2S4 2002-11-15 12:41:09 (548 views)

I read it on the internet.... ;-) - Mirror|rorriM 2002-11-15 14:18:17 (565 views)

It's not wrong, trust me :-) - Toy_Guy 2002-11-15 12:43:49 (631 views)
