Local RallyX driver Eric was hunting for a narrow 15″ wheel to run his Rally SG 185 15″ tires. The Speedline Corse Racing2000 in 15×6 +50mm offset fit the bill. Unfortunately it was a challenge to find confirmation of clearances. He ordered the wheels from Canada.Continue reading Speedline Corse Racing2000 Subaru 4 Pot clearance

Hey everyone, it’s been too long since I’ve posted anything at all. A mixture of life, racing, and work have slowed down the updates. Hopefully more to come in the near future.
I’ve had a spreadsheet for a long time that I pilfered and highly modified. It’s a full transmission calc with editable fields for Tire diameter, final drive and redline/shift point. It’s come in handy multiple times.
Mind you these are theoretical numbers based on math, real world figures may vary slightly dependent on actual redline, true rolling diameter of the tires and accuracy of your MPH devices. It’s a great tool.
It’s published on a public google sheet and you can download it if you’d like or edit the blue variables and see live changes to MPH. I’ve included columns for numerous different examples if you wanted to see the comparison between a 25″ and 25.7″ tire or compare the difference in MPH based on redline.
Enough chatter, here’s the link.

Any questions or comments don’t hesitate to fire them off our way.
This week we’re focusing on the popular wheels in the Enkei Racing line. We’ve covered the RPF1 already and it’s time for the NT03+M. The NT03+M is a popular wheel yet a challenge for many. The Concave face version is highly coveted for the style yet it has brembo clearance issues. The convex face version is not nearly as popular but offers great sizing in 17″ and they can usually be found used for very cheap.
Long time no post, I’m coming back with more info here in the coming weeks. If there are any topics or featured cars you’d like me to cover comment or shoot us a message.
One of the most common questions I see online is, “Will xx RPF1 clear my brembos?” Time to compile some data so it’s easy to find.
Here is a comprehensive break down of the Enkei RPF1 Brembo clearance for the STI brembos with their spacer sizes where necessary.
Hey everyone, going to keep this one short and sweet. Had a great event the last weekend of July. This week it was back in Oskaloosa at the airport. The day was a bit windy (as you’ll hear in the video) but other than that the weather was awesome. We got a total of 6 runs and enjoyed a really fun layout with a fast cross over. I was having issues with the start, but that’s one of my weak points. This run I got all data to sync up and work!! Check it out. (click continue reading to see video and pics)
