Midwest Tour

So I’ve been travelling the Midwest the past few days to visit some of our manufacturers.  First, I went to see our suspension parts being made.  They have a large facility with a lot of CNC 3 and 5 axis machines, lathes, mills, benders, water jet, and welding stations.  This is only about 1/3 of the whole shop floor.

IMG_8242They can do just about anything you can think of

IMG_8239Being able to do MIL-spec work, they are certified in just about every material, which shows in the stock they have

IMG_8243I have been discussing with them the idea of building our radiators and oil coolers.  They showed me the Denso core we would end up using for the FR-S/BRZ/GT86.

IMG_8245Then I went to visit our in autoclave composite manufacturer.  The tool for our SEW V2

IMG_8317Their large autoclave is 10’x20′, and is one of the largest in the country.

IMG_8312They work with teams at the highest levels of racing in the US as can be seen here

IMG_8326Since they had a bunch of defense projects laying around, I wasn’t able to take more pictures due to security reasons.  Then, I got to catch up with some of my old college friends and was told they were going to a 7 post rig test at ARC, so I watched that as well.

20130516_144147ARC also has a wind tunnel testing facility, but the team I was visiting didn’t have any wind tunnel time booked, so I didn’t get to see that.  Because the body panels were off the car and the guts were exposed, I couldn’t get any pictures of the car on the rig.  Sorry.  It’s been a very enlightening last few days, but I can’t wait to get back home tomorrow.

Rear Toe Link Install

Finally got the correct rod ends, and installed the rod ends.  Here’s a picture of the OEM link vs the Hancha link

It went very well.  A potential issue was that with the castle nut, the shank is too long and doesn’t leave clearance for the parking brake cable.  So we’ve changed the production version to use a nylon locking nut which allows us to shorten the shank by 10mm.  This also allows us to shave off a few more grams.  The toe link will head into production next week.  Expect these to be ready to ship mid-April.  This is what the final production version will look like

The Little Things

So we finally got our BRZ/FR-S/GT86 rear toe link prototypes back and I did some test fitting tonight.  Everything looked great

except for one small issue.  Like an idiot, I accidentally ordered the wrong size rod ends.  So I have to exchange them for the right size before I can test them on a car.  However, I still wanted to check the shank since it’s the most critical component of the part.

If the taper is off even slightly, it will move around in the knuckle and the shank will eventually break there.  I’m glad to report back, it was spot on and fit perfectly.  Unfortunately, Jimmy was taking pictures of me, rather than the shank.

One thing I did discover is that there is not enought room between the trailing arm and toe arm to build in bump steer adjustment into the shank.  Therefore the feature will be removed.  Doing a comparison of the OEM toe link vs. our toe link

IMG_8191I will test fit and test drive with the links on the car as soon as I can get the right rod ends.
