The Toledo ProSolo is always rough on cars. Combine incredible grip with intense heat and you've got yourself a potential recipe for disaster but thankfully Bumblestook held together to take the win last week. However it was not without issue. I had trailer wiring issues and had no trailer brakes most of the way there and back and Bumblestook's handling felt a bit inconsistent so it was time to get her back on the lift to give her a good post big event maintenance at
SJF Performance.

First though, her win gave Bumblestook dibs on the new Jet Hot ceramic coated
Toda Torquie-Kun Header. While I purchased this header for
Lupa, it made more sense to put her in Bumblestook where I can hopefully use it to get even more usable midrange torque as well as keep the engine bay a bit cooler.

Installation was pretty smooth. The runners go out a bit further than the PLM header so we had to insert the header from the engine bay but fitment was excellent. Of course, new gaskets were put in for a proper seal.

SJF then flushed the diff fluid. The Toledo ProSolo was only the second event on the new ATS Spec III Type DD diff so it's just basically broken in but the diff fluid coming out was extra dirty. Hopefully it's just break-in carbon from the clutch plates but the diff itself seems to be having well and I'm not hearing of feeling anything unusual so I'm not too concerned. Once all that was sorted, she was put onto the alignment rack. The alignment had definitely shifted quite a bit and after talking to SJF, we decided to try a pretty different and perhaps more aggressive alignment this time around just to see how it would change things. We went with much more camber up front and a hair of toe out for slightly faster turn in. In the rear, we reduced the camber a smidge but still kept the 1/16" total toe in for stability.

| Got Camber? - SJF Performance - 6/20/2017 |
The new alignments specs are:
Front:-3.7 camber
5.4 caster
0.04in total toe out
Rear:-2.3 camber
0.06in total toe in
When we went to reset my sway bars back to meadowlands settings SJF noticed that the nut on my front sway bar was missing. The bar was definitely connected on Saturday in Toledo so somehow between Saturday and Sunday of the event the nut vibrated loose. The funny thing is I was struggling with understeer up until then so it's almost like Bumblestook just fixed herself for me by disconnecting her own sway bar haha. We reconnected it and dialed the front bar down from 5/6 to 3/6 and set the rear bar back to full soft from 5/7.

| Added exhaust hanger - SJF Performance - 6/20/2017 |
I'm not sure if it's the new header or the fact that some stuff shifted but the exhaust tip was touching the rear bumper. To move it back into position, SJF welded an additional hanger onto the exhaust to pull it back towards the driver side so now there's no more play left and right. That was it for all the Bumblestook upgrades and fixes. The final thing to fix was the wiring/overload issues with the trailer. I suspected the issue was related to the trailer connector so that was replaced with a beefier heavy duty one and so far the trailer seems to be operating correctly again.

We don't have any events until the end of July so Bumblestook will be off to Evans Tuning next month to get a quick retune for the new header to make sure she's 100% when we go to Nationals.
