Now that a few companies have developed some parts for the 2014+ cars, I'm thinking about doing some mild STF stuff to make the car a little more interesting--not necessarily more competitive. Looks like Racing Beat and Corksport have bars…now we just need shocks and springs and...

Good blog Per, thanks for sharing. I'll check in from time to time to see how things progress. Be sure to update after you put the new front bar in or any other changes.

I hope to eventually see you in STF (and I think we will ). Even many of the Mini guys are moving on from HS because the Fiesta ST is just too much of a powerhouse. I'd be surprised if Tim C stays in HS with the Mini. Also on local events where we tend to race against others on pax, you got an uphill battle in HS because your index in the future will be based on a smaller car with 50 more hp and 50 more ft/lbs of torque. Either way, best of luck this season and hope to see your Mazda3 out there.

Yep, you'll see me in STF.

16x7.5 wheels on the way….
225/45R16 R1Rs in my garage
Racing Beat bars on the way…
Trying to work out spring/shock package now.

Bear in mind that this car sees 100 miles a day of Cleveland, Ohio roads, year round…so it's going to be mild-ish.

Sweet!

Hey I can respect that. Glad you joined the STF club and looking forward to seeing the build unfold. Kind of interested to see what is out there for a 3rd Gen Mazda3.

The short answer is…not a whole lot. I will have an update soon--whenever those bars get here.

Updated the title to reflect STF class.

Awaiting camber plates now. Have rear bar installed…will be installing larger front bar shortly. I've done the testing on a bunch of MacStrut cars and unless you go stupid on the spring rates, larger front bars actually help reduce understeer. For example: http://grassrootsmotorsports.com/articles/roll-with-it/

more updates shortly.

If using a spring/shock package, how much gain do you anticipate with the camber plates?

I'm desperately after some camber myself, so thinking of adding a bigger front bar to keep what camber I have and then either going plates or slotting the tops...just not sure how much I can gain with a full-size spring. I know you also get to work with the more raked strut with bottom bolts. grr!

I doubt that I'll see more than 1.75…with the 6 degrees of caster, that's good, but not great. I'd rather not use 'crash' bolts on the bottom, unless they're factory--which hasn't happened yet.

Increasing the front bar will increase understeer, so you might want to adjust the rest of the car to keep the balance as you like. I think the saying is something like one happy tire is better than two unhappy tires, so people with miatas and BMWs (really any RWD car) run a stiffer front bar and may even lift a front wheel through a turn. Sadly with our cars, if we lift a wheel we aren't putting any power down so be mindful of this. I'd be interested to see how the car performs with a stiffer front bar as compared to increased spring rate. I don't know if any STFers on here have tried that route; Adam actually went smaller IIRC.
