We’re back again with more Brembo clearance info. The Enkei RPF1 is a popular wheel choice, it comes in many different sizes. Unfortunately many of the popular sizes don’t clear the STI Brembo calipers. We’ve already gone over what’s needed to clear the 17×9 +35mm, 17×9.5 +38mm, and 18×10 +38mm. Next on the list is the Enkei RPF1 18×9.5 +38mm. For the 18×9.5 +38mm Enkei RPF1 to clear the STI Brembos you’ll need an 8mm spacer. Luckily for the Subaru ownersÂ not runningÂ Brembos no spacers are required.
Say hello to the GramLight 57C6. It’s a classically designed 6 spoke wheel. GramLight chose to go extreme with the faces for the 57C6. Going wider on the 57C6 to get extremely concave, so much so it causes some caliper clearance issues. Luckily with the help of a consulting client and our friends at Penguin Garage we were able to get some test fitting. Below you’ll find the breakdown of the available sizes and the known issues. Plus a few pictures!
SCCA ProSolo and Solo2 Autox classing can be excessively confusing for the un-indoctrinated.
The SCCA Solo2 Rule book is a cluster of rules that attempt to properly categorize each vehicle into “fair” classes. We wont be going into detail on how well they are doing this. This will simply explain the current Class organization structure and basic legalities of each class in regards to the Subaru Impreza. This will also apply to other vehicles but there maybe some minor discrepancies, any questions can be emailed/commented to me or brought up on any of the many National and Local SCCA forums.

Owning a 2005+ Subaru Impreza WRX STi isn’t all smiles and boost. There are a few things that are prone to failure, luckily all of them are well known.
1.) Inner CV Boot on passenger side likes to die at 55k miles
2.) Stock Pistons aren’t bulletproof and can have failure under poor tuning conditions
3.) Oil Pickup failure
#1 There isn’t much you can do except enjoy the car and fix it when it finally decides to tear
#2 Get a good tune as soon as possible, don’t risk a poor tune even for a few highway pulls, get a pro tune and enjoy the car.
#3 Oil pickup failure isn’t something to be taken lightly, unfortunately if and when this failure happens the engine is toast. The Oil Pickup will crack, and it will no longer do its job. The crack will starve the engine of oil and you will cause catastrophic damage. Luckily, there is a solution. Killer B Motorsport developed a more robust Oil Pickup that wont crack!
What build has a Varis Widebody, Volk TE37SLs, R888s, JRZs, Fully Built Block, HUGE Twin Scroll EFR Turbo and 544k views on his IWSTI journal?
Still not sure?
Unless you’ve been living under a rock you’ve seen this car.
This build is none other than….
Enkei RPF1 is probably the best wheel in the world. LOL, kidding, but kinda serious. It’s one of those wheels that has stuck around for ages and every year we figure a new car they work on. Hell Enkei still comes out with new sizes or bolt patterns. Ranging from a 14×7 to an 18×10.5 they’ve got nearly everyone covered. Alright enough about Enkei and lets focus on the specific size on hand. The 18×10 +38mm is normally 5×114.3 but there have been a few special order runs in 5×100 not many though.
The 18×10 +38mm requires a 5mm spacer to clear the STI Brembos. Some people have gotten away with a 3mm spacer, but it’s too close for comfort in my eyes. I also believe it’s smart to always run extended wheel studs in conjunction with spacers.
