Default 2 q's (SM solo)

Q1

My local region evidently noise checks the exhausts. Im going to SRS full catless. I assume this will be louder than 93db? worst comes to worse i have the full 02 wrx exhaust.

Q2

So i know the wider the wheels in general the better. Is there any advantage to running 16x7 on 235/50/16 over 17x7.5 235/40/17? +43 and +45 respectively. I've also read somethings where it actually says 225 is better than 235+ for the 17x7.5. From what i read, 17x8 245/40/17 is just undoable thanks to the land of room in the rear fender.

Gc specific with rolled fenders and coils.

appreciate the help.

Hard to say if it'll be over 93db. Too many variables.....If you're at all concerned, leave room for a turndown on the end so you can direct it to the ground. Personally, I wouldn't worry until it becomes an issue.

If you're looking to get the absolute best performance in this department, you're going to be looking at wheels at least 8" wide and should be looking at 10" wheels. I've run 265-45-16 on 9" wheels as well as 285-30-18 on 10.5" wheels without cutting the rear fenders. Your alignment, springrates and rideheight play key roles in fitting massive rubber in the back of the GC. Depending on your brake setup, you may find the 275-35-15 Hoosier to work excellent on a 15x10" wheel.

I run 275s on a 17x8.5. Not ideal, but better than what you are thinking about doing.

And from what I hear, the 15s only clear the bugeye brakes.

The AS guys squeeze them on 8" wheels. It isn't as hard as it sounds. I say it's not ideal because you get a better footprint from a wider wheel. Obviously the AS guys can't do that, and I don't have the money to pony up for a set of custom wheels.

i checked the OP's other posts. sounds like his first or second year autoXing. I think most of the suggestions are beyond his capabilities for a few years.

JDMFLCL, please post a full description of your car. i still stand by my recomendation in your tyre&wheel forum thread.

Even with no muffler Subarus are fairly quiet. My straight piped STI was no where near the sound limits in my region.

the 16x6.5 split spokes? or the jdm 15" wheels froma v2? any of the 16" wheels basic 225 width Rcomps are a good start. u will ahev to decide what will be ur daily driver wheels. u may want to use the new wheels for teh Rcomps and keep the current ones for daily driver duties.

starting off on the r888/ra1 will be fine. street tyres will help u learn not to over cook the inputs.

yeah just the stock 02 usdm wrx wheels

See i was planning on having a set of DD's on the WRX and buying a new wheel/tire set for AutoX. so you think a 225/XX/16 on a 16x7 wheel would be a good start?

I guess im being forced to run in SM because of the swap

You should really just run your first few events on your street tires. Once you get the swing of things, then you can start to plan out what wheels/tires you want.

id like to do that, but unfortunately, i'd like to be as on top of my monetary expenditure as possible, and ruining my current DD tires at a faster pace isnt exactly in my wallets best interest. I'd rather maintain my DD tires longevity and get something specifically for AutoX.

The exception to this is Driving school where ill need to drive out on my DD, but asside from that, id like to make em last as long as possible.

As much as I agree with you on saving the streets as long as possible, the cost of a race tire setup with a second set of rims is pretty high (roughly $800). If you are fine with spending that much up front go and pick up a cheap 17x8 (rota or 5zigen) and a set of either Dunlop Z1 Star Spec or Bridgestone RE01R in 235/40/17 (if you can find that size). Run the season on street tires to learn how your car handles. If you're still into it by the second year, then look into R-comps.

I was in the same boat as you a few years ago, swapped GC with 225 Hankook RS-2's on the STi rims (7.5 inches wide). Luckily for me my region has a Street Mod Street Tire class so I continued to run street rubber (255/40/17). I'll still run it for next year, and it won't be till my 4th year that I go to slicks.

thats exactly what i was planning on doing. I have the 1k allocated...its not that i dont have the means, its just i'd rather delay having to use it. Im totally cool with getting a second set, i just would like to preserve my DD+wheel package as long as possibe.

Essentially before i bought the GC, i made a budget from the sale of my last car, and i allocated 1k for this. (tire+wheel setup)

Set of street tires - $400
Set of race tires - $1000+

However, if you are talking about a second set of street tires that you use only for racing, then I can understand. Even though most of the guys I know will run a set of Azenis for the whole summer, including all events.

Please, please, please, PLEASE read this next part carefully:

There are many, many people here that have been racing different things for many years (I have been autoxing for 8 years), and we have all been where you are. We have all tried different things. When everyone is telling you the same general thing, it's probably because when someone told us, we didn't listen, and had to learn the hard way. Now if you are one of those people that must learn everything on their own, then so be it. But when you ask us for advice, what you are going to get, once you wash away all of the opinions, are the lessons that have already been learned.

im talking exactly about buying a 2nd set of street tires+wheels for autoX

In summation, the general train of thought seems to be autoX the first year on street tires, then upgrade to something better...something i'm totally willing to do.

Sorry if i came across as "not listening", its just i work hard for my money and i don't want to see it go to waste and get burned down the road when a better option couldve been had. From all the input, and overall reviews of the tires ive been looking at, it seems that something like a direzza star spec or Advan S drive high performance street tire is the way to go performance and wallet wise. then in my 2nd or 3rd year of AutoXing just buy an R comp etc...

I appreciate all of the help and input. The 17x8 rota or equivalent cheaper wheel + one of the afformentioned street tire setup in 225/235 seems to be the most attractive anyways to me.

Don't forget Falken rt-615 and the Hankook z212. Both cheaper than the Dunlops, and better than those Yoks. Sure the Dunlops are probably better, but you will likely not notice the slight difference in your first year, and they will save you maybe $50 per tire.

Not to mention that I think the Azenis last longer than the Dizzeras

do atleast an 8inch wide wheel. I'm running at 8.5.

and I personally think you should do atleast a 235 if not a 245+ I'm running a 255 but I'm on coilovers which gave me the room to run a 255
