The toughest part about driving those full tread tires is that the quicker transitions are so sloppy. The treadblocks distort so much that you have to countersteer against the giant slip angles they generate even just straightening the car out.
Also, they necessitate early turn-in to give them the time they require to react.
And with that much power, you can see the chassis just sort of wandering around down the straight.

Great story! Looks like you guys had a lot of fun! What size wheel and tire combo are you guys running by the way?
If you're limited to the RA-1's, might as well shave them and go as big as possible.
The 275/35ZR18 is only an inch taller than stock and at your speeds probably won't effect gearing too much.

Next time Phil is just going to have to take the long route cross-country to wear them down more.

We are running 17x8.5" Volk CE28 wheels with 235/40-17 we got from World One Performance.
I was seriously thinking of stepping up but I was worried about the rolling diameter since we had to go with taller gearing. The straight cut PPG Dogbox gearing is significantly taller than the helical dogbox we ran last year so I had concerns about turbo lag.
Weight is also an important issue. Those tires are 6 lbs heavier a corner and the wheels to carry them are about 2 lbs heavier. Overall traction would improve I'm sure but 8 lbs of un-sprung weight per corner may have been very detrimental since we didn't have independently adjustable suspension.
There's definitely a performance edge to shaving them and surprisingly the tires wear very little on the highway. I wasn�t expecting that.
Thanks,
Phil

Oh, by the way, after all the driving was done, Phil asked me what I thought about the steering quickener. I told him that I wasn't even aware of it. He and the rest of the crew looked at me in disbelief, then went on to tell me how sensitive the steering was.
When something feels right while I'm on track, it becomes invisible to me. My attention is drawn to things that are preventing me from making the car do what I want it to. The steering felt completely natural to me and I was totally unaware of a device that was quickening the steering ratio. Pretty cool piece.

I know that the gains become ever more decreasing and then price ever more increasing. But I seriously think the car is just plain undertired. I would take the weight hit for the added contact patch. And again, the shorter sidewall is going to help transitions.
I was going to recommend the 305's but figured the logistics of getting it to fit, not to mention the decreased gearing would probably be a waste of time.

Nothing is a waste of time if you win ;)
You're right the car doesn't have enough tire and frankly it wasn't set up for the tires we had since our setup was based on last year�s Hoosiers. With more setup time we could have made them work very well for their size.
A benefit of going to 18� wheels would be to fit larger front brake rotors since brake ducting is so difficult. Going wider on the front is fairly easy as wide body front fenders bolt on but the rear fenders would have to be cut out and replaced to run such a wide tire. I would consider this but then the car loosing some marketing benefits as it isn�t directly relatable to the general consumer. We may be able to go with a 265 width, lighten the car and still keep the OEM look.
As for the gearing we should be ok once we have an engine that will sustain a higher rpm range.

Phil

Are the wheels allowed to stick out from the wheels wells? Also, I would agree that hacking up either fender probably wouldn't be in the spirit of the rules anyway. I mean, it's supposed to have a similar sillouhette, but I doubt anyone would be happy if you should up with flares all around and 335's.
Good luck and keep us updated!

A sign of a good product! This has to be one of the best modifications I've made to the WRX. The steering is substantially quicker than the STI and even the EVO but it's not at all "twitchy." It gives a nice weighted feel along with excellent feedback.
At the time I received mine Crucial Racing was selling this steering �quickener� which is a gear reduction unit installed on the OEM steering column. There was a core charge which was refunded when you returned your unmodified unit. I want to say the unit was around $500 but more importantly it�s so easy to install as compared to replacing the entire steering rack.
This is a must have for you autocross guys!

I don't think you are allowed to modify your steering column even in SM. I agree it would be sweet if you could though.

Ok, it's official I double restricted the turbocharger's oil feed line causing the turbocharger failure. :furious:
After inspecting the custom banjo bolt at the block that feeds the turbocharger's oil line, it's already restricted so the second restrictor I added dropped the oil pressure and flow enough to damage the turbine shaft and bearing. The turbine shaft itself snapped and the compressor wheel is gone, most likely on the track or in someone�s grill. :lol:

Great story Phil, the in-car video is great!
I definitely agree with Gary about he RA-1's squirming with full tread; I ran full tread 235/40/17's last year at Summit Point and the slip angles were incredible. The car also liked to "wag its tail" under heavy braking.
So are you going to bring the car out to Summit Point this year?

Yes, I was hoping to sneak one last track event in before the end of the season but I just missed out. I would like to spend more time adjusting the suspension to suite those RA1s.

Phil,
Let me know when you are headed to the track next spring/summer. I will hopefully be attending all of the NASA HPDE's at SPR and VIR and would love to see your car out on the track again. When I saw you drive it at this year's hyperfest you were unfortunately stuck in a slow group, although what group isn't slow with 500+ HP on tap?
