General Setup Bad Ideas.

Well, I have some sad news to report after returning from Kenon last Saturday.

1) The front diffuser broke within 10 minutes of actual racing -- the small front lip got torn straight downwards resulting in a lot of scraping against the track. Couldn't get that bend out of it either, a shame...

1a) (Not sad news) The front diffuser worked like a charm, as expected. Toning down the initial steering response and increasing on-power steering, it's almost like running softer...

Diffuser Aerodynamics, Rd. 2 Pt. 2

Posted 11-13-2011 at 11:38 AM by color0
Sorry for skipping October, everyone, it has been a helluva school term so far (and not even for academic reasons!) and it won't be until January that I'm back to regular Mini-Z updates.

Anyways, the F430 is back from the Dr. Kustom shop and even with some racing wear it looks gorgeous:



It's probably stupid to run those large offset wheels (+2.5N/+2.2W! Didn't think it'd fit under an F430,...

Rear Diffuser Aerodynamics, Rd. 2 Pt. 1

Posted 09-26-2011 at 04:51 PM by color0
Recently I've picked up a new F430 body, but instead of choosing the ubiquitous F430GT, I bought the street-version F430 instead for two reasons:

1) The front bumper sits higher off the ground, allowing me to lower the front end of the car more with minimal plastic trimming. I don't like to trim the front bumper horizontally across the front as it's hard to keep it perfectly level. And keeping it perfectly level is the key to obtaining consistent aero properties across the width of...

Downstop/Rebound Spring Tuning

Posted 09-23-2011 at 02:42 PM by color0
Updated 09-26-2011 at 04:15 PM by color0
Last week I had a conversation with fellow SoCal Z racer mugler about tuning the downtravel on the top shock of a pan car chassis -- as you might imagine our conversation was very related to my previous post here about the downstop adjustments on the PN and Kyosho shocks. I tried my best to explain why and how the downtravel adjustment works and my reply is repasted below.

Comparo: Kyosho vs. PN Top Damper

Posted 09-07-2011 at 04:41 PM by color0
Updated 09-07-2011 at 04:44 PM by color0
...And welcome to the second edition of our series of parts comparisons. This time, it's about top dampers, specifically the Kyosho Oil Damper vs. the PN Racing Dual Spring Center Shock as adapted to my personal car setup. So yes, once again this is going to be strictly my opinion, and I don't think there is a totally superior product between the two of these. So think of today's article as a pros-and-cons list between these two great top shocks.

A little foreword to the rest of...
