Re: Thinking about building a car

I'm curious why you guys are even screwing around with the issue of 225s. It's a spec series. Pick a max size that is easily accomodated and everyone has to run on the same size. Who cares if it's 195 or 225? Everybody gets the same.

I'm not trying to stick my nose into your series, but I honest don't get this.

much of the problem lies in the fact that Rob (and most agree with him) doesnt want to make any mid-season changes (which would make the series look unstable) and Naji wants them NOW. 225s will likely be allowed, but for next season, giving everybody a fair chance to change their setups and not give anyone an unfair advantage.

First of all, SR isn't only 205. If you have a QR B15, you can run 225s. So, for some, 225s are already allowed. It is kind of like brakes- when we allowed the B15 with 11 inch brakes, we just decided to incorporate allowing 11" brakes for all cars. One argument to running 225s on the B13 adn B14 is that it would make things a little easier to administer- all cars run 11" brakes and all cars run 225s- and get group deals, etc.

Another thing that some have argued is that, while it is a spec series, we are not a series in a vacuum. We have to consider that a prospective new race has a lot of different series to choose from. If we can make the SR cars marginally faster and reduce tire wear at the same time, probably faster and cheaper would be a draw from some people. It is nice when promoting to say that tires will last half a season instead of just a few events.

A third consideration is NASA Endurance racing series, which many of us have participated in at one time or another. NASA usually holds 3 or 4 three hour endurance races and all of the NASA classes are condensed into a more compact set of Enduro classes. SR cars are in E2 with H4 cars, 944 Spec cars, etc which allow 225 width tires. While H4 and 944 Spec cars were running on their sprint race Toyos, SR cars were either burning through a whole set of sprint race tires or equiping a less grippy tire with better wear. Many of us would like to see the SR cars more competitive in E2, as that would be good promotion for the series.

Re: Why 225s?

Oh, one last thing. I don't believe the myth that it is difficult to get 225s to fit on a B Chassis. We fit 245s in the front and 235s in the rear on Jeff's car just by purchasing a different offset wheel and spending a few minutes with a hammer to the fender.

If you're building a car, getting the correct rims will basically cost you nothing since you'll be buying rims anyway.

Many people already run 225s on their car in competition. Greg Amy's B13 NX, Art Rinners B13 Classic, Naji's B14. What I don't understand is people that say, "Oh, 225s don't fit." That is an SE-R Myth that needs to die.

You'd be surprised how much clearance in on the CRXs. It is like they were designed for racing of something

Re: Why 225s?

true, but look at an EG hatch, and you'd swear it was designed to tease you with an awesome suspension, but no fender clearance for tires.

Yeah, it is funny for Honda Challenge they use to have a rule like "any width tire that fits under the fender when viewed from above". Now it reads something like "any width tire that mostly fits under the fender when viewed from above".

Re: Why 225s?

I have run 225 Kumho V700's with no problem. I would like to see one tire picked for the series. The 205/50/15 Toyo seems to be the best option and they are giving a better contingency if it's the spec tire.

You can already get a contingency from Toyo through the National Toyo Contingency Program: http://www.nasaproracing.com/news/toyo_2004.html

All you have to do is put on stickers and fill out a form that is signed by a tech inspector (usually at impound).

Anytime! I'm glad some of those reasons make sense.

Mostly its because Rob is against mid season rules changes and the chaos it can cause.

The controversy is that 225's are actuly slower than 205 but longer wearing and you don't have to have your race stratigy based on tire managment. In my testing I have found that the 225/50-15's are generaly about 1-1.5 seconds a lap slower than 205's. I feel that this is due to screwing up the gear ratios.

Which is why anyone running 225s would be a fool not to run 225/45-15s or the 225/50-14s which are almost identical diameter to the 205/50-15.

Let me just add that Team Dynamics just came out with 14x7 +38 offset wheel. I ordered a set for $115 per rim. I read on Honda-Tech forums that the wheel was designed for the ITA Hondas and rumor has it that it will clear 11 inch rotors. If this is true, then it is possible to run these rims on the large brake kit that is used by most in the SR class.

I also got my 225/50/14 Hoosiers and the tire is even wider than the 225/50/14 Toyo. It is amazing. We are talking about an inch wider. I hope they will fit w/o rubbing on the front strut. I heard that Hoosier tires are wider than the same size tires from other makers, but this is amazing.

I thought Hoosiers were not an approved tire for the SE-R Cup?

They are allowed in SRX. Plus I am running my car in the below 2.2 L modified class with TCRA and I need Hoosiers to keep up with the 914 Porsches. I also need 15 more hp and 10 lb-ft of torque. S5 cams and Gen6 headers should take care of that

Re: Why 225s?

the team dynamics wheels have a HUGE amount of caliper clearance.

we mounted some 15x7 +30mm wheels (thanks Naji) on Martin's Fastbrake equipped SE-L and had over 2" of clearance from the spokes to the caliper. i am not 100% sure about the 14s clearing the diameter of the brake rotor, but it looked like it had over 1", IIRC.
