It has been a long, cold winter and my baby's been off the road since February, getting suited up for a 9 race series starting May 4th. Here's the series we are running: http://www.300cforums.com/forums/road-course/103705-calabogie-gt-challenge.html

She's back home now. Not much left to do - mount summer tires (1 set for track; 1 set for daily driving); set up alignment front and rear for some serious negative camber on the track; then do some custom tuning on the ECM and probably install a Tranzformer TCM tuner to set up shifting at the track.

At the end of last season, we managed a 2nd place finish in our class and needed to address 2 important issues:

1. Suspension adjustments for more negative camber

Late last summer we put on adjustable front upper control arms



And immediately we started to run at the front of the pack as to lap times.

So . . . we needed a solution for the back wheels, as well. I was in South Florida in January, so I dropped into SpeedLogix in West Palm Beach to see Lisa and Mikey.

It just so happened, they had a brand new, custom engineered set of neat adjustable rear control arms -
Speedlogix Adjustable Billet Rear Control Arms 05-13 Challenger, Charger, 300, Magnum





Here's the rear cradle down with the new arms (black) installed



Hopefully, we'll get even more grip in the corners!

While we had the cradle down, we installed 2 new halfshafts, just as a precaution, as one has been leaking since an "incident" at California Motor Speedway back in 08. The shafts came from Speedlogix as well at a very good price.



2. Engine cooling! The 6.1 running at 4500 to 6200 rpm was overheating. This meant short-shifting and giving up way too much hp and torque to our competitors.

The answer, after much research, pointed to custom fitting a large Fluidyne cooler to a sandwich plate installed at the oil filter take off.

Here's the big new cooler, just after I painted her flat black (for stealth reasons :) )


Here she is installed above the bumper. We put in a new heavy duty rad, while we where at it:




Some of you may know that I have been running Eibach Multi Pro R2 coilovers and have been quite happy with them - until late last summer. The Pedder's sway bar ripped off the RF strut bracket. I ran the last 2 races with no front swaybar!

We contacted Eibach last fall. They asked us to send back the 2 front struts. They then sent us back 2 new struts with a heavy, redesigned lower bracket for the end link attachment. All under warranty.

Now that is service! Here is a pic of the new strut bracket:



This week we will put on our track rims; install 2 new tires and get everything aligned to race specs




Finally, a big thanks to Ian Madden, owner of Metric Auto Services in Ottawa - and a damn fast racer, himself!

I got my upgrade list out when I read this, bud. Thanks for some great ideas! The car looks awesome.

Excellent list of mods with race quality components, something to be proud of :yup:

I'm also digging the rear camber arms, not seen this type of component for the LX platform, I could only find camber bushing.

Its a winning setup :fing02:

You have an outstanding setup! Good luck in the upcoming race season. We all know you will do very well :)

Thanks guys!

I would not put this amount of time, effort and money into any car - unless the bone stock vehicle was already well suited to road racing.

The 300C - and particularly the SRT-8, certainly is. I think we will see more and more of the older LX and LY bodies showing up on road courses.

And here are some of the reasons why:

  • The Chassis is made from Hydro formed steel - a first, on a large mass-produced sedan. This ensures a very rigid platform with very little flex.
  • Chassis flex is the enemy on a road course. It will change the suspension geometry making the handling unpredictable, and that will compromise corner speeds and braking.
  • The Engine and transmission are very strong and reliable, with gobs of torque. Note that I have not done any mods in this area, except for a CAI; free flow exhaust and a chip tuner.
  • The overall quality and engineering seems to stand up well throughout the entire vehicle even under race conditions where we push up to 1.75 G's of lateral force in certain corners.
Out of the box, the car is fine for lapping on the weekends. If you want to step up into competition against Bimmers and Porsches, here are the areas that need to be improved:

  • Suspension Bushings - if your car has over 60,000 miles
  • Better pads for braking
  • LSD is an absolute must
  • Adjustable camber settings front and rear
  • Power Steering Cooler
  • Engine Oil Cooler
  • Adjustable Coilovers are nice - but not essential
  • Wide grippy tires
This car is so easy to set up for neutral handling and is so predictable under cornering, braking and acceleration. This makes it a joy to drive on a twisty track, despite its obvious size.

Can't wait to get back out on the track in 4 weeks! :)

It was pure 'luck' that I found these, at Speedlogix, as they had just been designed and manufactured.

Let's face it. There is not a big market of LX owners who want to be able to put serious negative camber on their rear tires.

We'll be on the track for testing in 4 weeks. should get a good idea then just how much difference the rear camber control arms can make to lap times.

Very nice, Looks like a blueprint for the rest of us. I sometimes think I should get a car that would be more track friendly, obviously I have one, I just need to get over the fact it also happens to be a large sedan. Thanks for reminding us what a capable platform we have.

Nicely done! Can't wait to see what improvement it all makes this season!


Waiting for your videos! :fing02:

A few more "Improvements"

We hit the track tomorrow for Test & Tune day.

Here are the latest Upgrades (guaranteed to make us faster)


A flat black wrap on the raised cowl to reduce sun glare as most of our races start at 6 pm.

A flat black panel on the back with a thin chrome trim around the BT custom wing





A mirror decal, courtesy of 17Vvet76 to remind me to 'hold the go pedal down' !






Finally, the artwork for a front windshield banner ( we haven't actually printed this yet)





It will be peel and stick and will run right across the very top of the front windshield. I'll run a few extra if anyone contacts me and wants one for their car (at cost)

Thanks for the quick list. I have been doing Autocross with my 300 SRT8 and it always looks out of place compared to the other cars, but it always surprises them with the times it turns in. I'm doing my first Road Course this weekend as part of the Heidts Performance Car Challenge. It will consist of Road Course, Autocross and drag race. I will add your list to my wish list for next winter.

Latest "addition" - Smoked Lexan headlight covers - guaranteed to streamline airflow and increase top speed - LOL!

Actually - just some protection for our pricey headlights - against stone damage - common occurrences on road racing circuits.

Looks even more evil. :fing02:

And at least 10 more HP ;)

Northern Rider, how would you rate the MOPAR Stage II suspension against the Eibach setup that you're currently running. Beautiful car, by the way!

:notworthyWOW what a GREAT SRT8... That's fantastic PATRICK. I would hate to see you in my Rear View mirror on the TRACK. Seeing the BLACK BEAUTY 2 Running for war would be AWESOME. GOOD LUCK:notworthy
