For those that wanted to see some "balloons" on the SI BUS....
No rubbing from lock-to-lock and the only clearance "issue" was the plastic fuel hose cover. (less than 15mm of clearance) but does not rub.

haha. you're about a year late on this one!

i've had the avs es100's in 225/50/15 on my car for about a year now. they're down to about 25% tread left. :)

In the rear, with my +37 offset wheels, in order to run -1 camber I had to trim the fenders. not a big deal though, now I could probably get 235's if somone made the size. :)

next time, i'm going with something grippier than the es100's. they're okay for the money, but they give up a lot in terms of grip to the azenis, ecsta mx, and the other top tires.

Jack, how wide are those rims?

Ocelaris
09-26-2003, 11:22 PM
Yeah, are you dropped any? wondering if my KW coilovers dropped about 2" is gonna have clearance with 225/50/15 ? Yeah, rim width please :) anyone know the largest width that will fit oem 15s?

What about 225/45/17? That be hot! I guess nobody makes a 225/40/17... If 17" aren't in the forecast, can I just get high offset rims to fit the big brake kits? I thought it was the calipers that had fitting issues.

Tire1 = 225/50/15
Tire2 = 225/45/17

Section Width1: 8.858 in 225 mm
Section Width2: 8.858 in 225 mm
Rim Diameter1: 15 in 381 mm
RimDiameter2: 17 in 431.8 mm
Rim Width Range1: 6 - 8 in
Rim Width Range2: 7 - 8.5 in
Diameter1: 23.85 in 605.79 mm
Diameter2: 24.97 in 634.23 mm
Sidewall1: 4.42 in 112.26 mm
Sidewall2: 3.98 in 101.09 mm
Radius1: 11.92 in 302.76 mm
Radius2: 12.48 in 316.99 mm
Circumference1: 74.92 in 1902.9 mm
Circumference2: 78.44 in 1992.3 mm
Revs per Mile1: 872.1
Revs per Mile2: 832.9
Speedometer1: 60 mph 100 km/h
Speedometer2: 62.82 mph 104. km/h
Speedometer Difference: 4.706% too slow Diameter Difference: 4.49%

from www.1010tires.com good calculator, didn't look at $ amount

So it looks like the diameter of #2 is like 31mm or 3.1cm bigger, and the OP said he had only 1.5cm clearance... so is that a no go? damn and blastic all

Whether a kit fits a stock wheel is dependent on the specific application. Our ST-40 four-piston caliper usually requires a minimum 17" wheel size for a 332mm (13") rotor and a minimum 18" wheel for a 355mm (14") rotor. If a 380mm (15") rotor is uses, a 19" minimum wheel size is likely necessary. More important than the diameter is the clearance between the face of the caliper and the inside of the wheel spokes. Wheel width and offset have nothing to do with this clearance area; it is strictly a function of the spoke design. We have detailed templates on our website that will allow you to accurately test fit any wheel. Be sure you check wheel fitment BEFORE committing to a wheel set or big brake upgrade. Here is a link to the Wheel Fitment Charts: http://www.stoptech.com/wheelfitchart/wheelchart_index.htm.

and they have one for us:

http://www.stoptech.com/wheelfitchart/PDF/civicsifront.pdf

I would assume their ST40 calipers would be similar sizing to the Brembo or AEM big brake kits with 13" rotors...

sorry, I guess this is straying a little off topic, but in my figuring out whether I could get those 225s on the 17"ers... taking into consideration wheel clearance/rotor caliper clearance is all in the game.

he's in it for the performance. Bigger rim means bigger rotational mass and slower car.

hey where did u get that small tachometer by the steering wheels?

I know about the unsprung/rotational mass issue. But you need bigger wheels for bigger rotors.

In your estimation would stock sized rotors be just as good as 13" rotors? I don't think so, but I could be wrong. smaller/ rims = smaller rotors = worse braking. I don't think it was fair to say "he's in it for the performance" implying I am not, where as an educated compromise on unsprung/rotational mass for better braking is "not in it for performance" if anything it seems to me that is a blind way of thinking of "performance" going fast without any consideration of howto stop.

what kind of racing do you do?

b/c bigger rotors do NOT = better braking, and smaller rotors do NOT = worse braking.

before I comment further, i'd like to hear about the type of racing you do.

Ocelaris

I don't do any racing, and I probably will never do any racing. My goal is also performance, but I know I'm not going to have the money to make my car that much faster, so I'm making sure I have "enjoyable to drive" down first, engine mods are more expensive and/or more difficult to learn about. I.E. there's not quite a stop tech faq on engine performance, where as I can take the whole "brake" section and learn about it at once, as opposed to "engine" which is such a huge topic it's hard to find any place to get a overal idea of it.
I'm just trying to work my way up piece wise. I will probably do drives through the back roads, which you might compare to auto-x.

So you're saying bigger rotors do not play a part in better braking what so ever. correct? I don't know, and am ok with that. Then why do they even offer bigger sized rotors? just for increased heat dissipation? I know I don't want high temp racing brake pad compound, so if bigger rotors are only for heat dissipation, then the point is mute and I'd just assume get 225/50/15s ... Are the stock rims long enough to handle 225?

If that's the case, that's great news for me, because I've been postponing any brake upgrades because I couldn't afford new wheels+tires now, with brakes I could scrape together 100$ here and there to get new hoses, fluids, etc... one at a time. Assuming of course I could fit 225 or 215 on the stock wheels?

But what about say the stoptech kit for our cars, that requires 17" wheels right? I mean, I just remember switching from my old saturn to my sister's jetta one time, and realizing how much better braking matters, not that either of those have particularly good or bad brakes, just that it left a big mark in my mind in what I wanted.

So my requirements are good cold braking (after warm up), dust doesn't matter as I wash my car frequently enough, probably 75% of the time I won't get the brakes warm enough to use racing compound. Noise isn't a big deal, I'll tolerate it for better stopping.

I guess I may be confused in what helps braking. Can you replace the calipers to get more clamping strength? But you don't need larger rotors if you're not going to do alot of racing? I would like every once in a while type capability, and/or the chance to upgrade if I ever decide to.

This is all a learning experience, I guess I was frustrated that my assumption that you needed bigger rotors for better braking, means I'm in it for bling... And I don't think racing is a requesite for wanting function over form. I am in the same mindset performance over looks as you all, or I wouldn't have been as excited about the whole 225 thing in the first place.

Nice job, and excellent choice on the wheels. But, those AVS ES100 Yokohama's are also offered in a 225/45WR16 size. The shorter tire has a wider tread width than the 50 series, 8.7" v. 8.3", and it's lighter. The 45 series would also have a gearing advantage.

Those are 15x6.5 Konig Heliums. They weigh just about 11lbs with balancing slugs, and cost around $120 each from Discount Tire. The are a copy of a volks wheel.

How do I know? I enjoy a set my self....good alternative to Slipstreams or C-8s, but theyre not available in 16s or 7" widths.
