An Evo X Weekend At Buttonwillow Raceway
Everything else was left stock. With just 3 hours of sleep after prepping the car last minute, we made the trip out to Buttonwillow. With 100-degree+ weather out, it was a tough weekend.

This particular Lancer Evo 9 was born as a Sport Compact Car magazine project car. From those days on, this trusty Mitsubishi saw the skidpad, figure-8, drag strip, road course, autocross, track days, and time attack competition.
It still needs the accessories, head, turbo, and oil pan to be swapped over from our old engine. Needless to say, it didn’t drive to the Mitsubishi Owners Day 2010 show.
Faster on track than a Porsche 911 Turbo while using full tread, wet weather capable street tires. Once we play further with spring rates, alignment and other adjustments, we’ll be able to pick up even more speed. Simply. Badass.
Project Evo IX’s last track outing did not go well. On top of being outgunned power-wise in the Street AWD class (our 350whp stock turbo setup always is), we discovered that our rear limited-slip differential had given up the ghost.
We knew that we wouldn’t have the time or the budget to strap on a bigger turbo or a fancy carbon fiber rooftop before we left. We’d be facing 600whp monster Lancer Evos again with our daily driven 350whp (on race gas) street car. Not a problem for the constant underdog OR team, right?
The NT05 is Nitto’s latest maximum performance offering. With a low UTQG rating of 200, it’s matched up against the usual SCCA Street Touring standouts like the Falken RT-615, Yokohama Advan Neova, Toyo R1R, Hankook RS-3 and Dunlop Direzza Sport Z1.
For the average real world driver, the Continental ExtremeContact DW provides a better balance between cost and performance and will provide more than enough grip for the street and, occasionally, the track.
The Yokohama Advan Neova tire displayed high grip and sharp steering feedback on track, especially through the very quick Turn 2 (average 87 mph) and Turn 8 (average 119 mph) areas.
After the last two time attack events at Willow Springs International Raceway, two things have been bothering us – how can we make Project Evo IX faster and how can we do it without spending a lot of cash? By optimizing the car as much as we could
Toyo sells other tires for those purposes that are both quieter and longer lasting. The R1R is an r-compound racing tire disguised as a DOT street tire. But if you’re interested in putting every last bit of power down to the ground or autocross in the SCCA’s Street Touring class, then please read on.
At the moment, it seems most tire companies just want to go to war in the performance street tire market. With outright handling records and SCCA Street Touring autocross national championships on the line, numerous tires have been released with 180 or lower UTQG ratings.
We didn’t take the Formula One world championship, run through the Monte Carlo rally or convince the ALMS to make an exception for our entry. We’ve been storing up our dwindling cash reserves since the last two time attack events and planning for what’s coming up next this season.
A completely stock engine is coupled with a turbo-back exhaust, ECU tuning and Greddy boost controller, JIC coilovers, Whiteline roll center kit, Ferodo/Performance Friction brake pads, custom modified APR wind splitter, Recaro seat and Voltex rear wing. If it seems like we went insane with our budget, we didn’t.
The last time you read about Project Evo IX (Part 6), we won the Street AWD class at the Super Lap Battle Willow Springs event. Our Mitsubishi project was loaded down with only the best in factory stock equipment – stock engine, brakes (with pads), turbo, intercooler, piping, cams, ECU, body and airbox.
This is Project Evo 9 – a daily driven (by myself), street legal and fully registered Lancer Evolution IX. As of the 2009 Redline Time Attack Willow Springs round, it’s also a podium finisher.
The dust has settled and we’re honestly too happy with our results to hide them, we’ve won Street AWD at the Super Lap Battle Willow Springs qualifier event. With just a few days, albeit long days, worth of work, we’ve gone from bolt-on street car to time attack competitor.
Lancer Evolutions are not slouches, even in factory form, and commuting through stop-and-go traffic in an Evo does a disservice to the car itself. But competing in time attack, i.e. time trial, competition so early in its development was not on the books for Project Evo IX.
Called the “fastest track in the west”, Willow Springs International Raceway in Rosamond, CA has just nine turns and plenty of straightaway space. Cars that have lots of horsepower, stability and minimal drag often do well, with only the fastest production-based cars dipping into the 1:20s.
In our last few installments, Project Evo IX saw minor modifications that didn’t, in our opinion, affect its day-to-day drivability at all. A stiffer and lower suspension system added a bit more impact harshness, but it was definitely useable. But none of them were real “racecar” modifications.
