You suggest avoiding steel wheels. Is that to minimize unsprung weight?
No, it has to do with durability and longevity. I'd also think you'd have a hard time finding steelies that would clear the larger brakes on a B15 SE-R.
To minimize unsprung weight, don't run rally tires! After the weight of your typical rally tire a few pounds here or there in the wheel starts to look meaningless.
Really, for your typical SCCA-type rallycross event (low speed, tight course, dirt/gras/smooth gravel) you're going to have better results on snow tires (ala Bridgestone Winterforces, and not so much ice tires like Blizzaks).
There is a desire to run rally tires that I can understand, because that's what the real rally cars run, so that must be better, right? But rallycross isn't stage rally.
I've run both, and the snows are the way to go with a couple of caveats. If your suspension is so limited in travel (and the B15 is not too bad compared to the b13) or your dampers are so worn out, that the tire ends up absorbing a lot of the force that the suspension is supposed to be doing, you will de-bead a lot of tires running street tires. that's not only inconvenient, but dangerous.
I came inches from rolling my rallycross car (B13 SE-R) when I hooked a fairly minimal rut and de-beaded the tire, causing the rim to dig in. If I hadn't already been counter-steering for the next turn, I would have gone over. I was running OEM struts that were completely worn out, and actually had wedges in my springs to increase the effective rate (transferring even more impact into the sidewall) at the time. I was also driving at the very limit chasing a championship. Afterward I got rally tires, and didn't de-bead them, but the unsprung weight and rotational mass was very noticeable in the performance of the car.
Eventually I got a decent set of AGX's for the car, pulled the wedges and went back to snow tires. Much, much better all-around.
You're suggesting if the spherical lug nuts could be found in the right thread the Accord wheels would be an easy fit?
Well, they'd be plentiful. You'd still have to have the center bore enlarged. Craigslist (at least around here) seems to be half ads for kids trying to sell the stock wheels off their '90s Accords.
Just want to clarify that. I guess I'll start looking for some alloys or used rally wheels off a 240
You'll probably have good luck with people selling their 240sx wheels, as nobody wants to roll on stock in that crowd
In a junkyard you'll probably find more in the way of Altima wheels.
