I apologize for audio. But I wanted to share info on this topic. As we are always told DC2 will always be faster which is not the case.

So just continuing on after watching your video there is a couple of things I should mention. I spoke with the Chap who built my DC5 and he said the DC2 is technically a better car because of the A-Arm Suspension vs the Macpherson of the DC5. He went on to say 'the Mac suspension has problems but it can be improved to a point where it's acceptable but the the A-Arms of the DC2 will always be better'. That said HardRace in Sydney Australia have a suspension solution for the DC5 which improves things greatly.
The other big improvement is the Delrin Spacer by SHG. SHG'S Delrin Spacer bolts in under the Rack Raiser gets rid of the vagueness and wandering steering. When you pull the stock one out and compare to the SHG you will say 'OMG'.
Main problem with the DC5 is when lowered (and my race car is lowered a lot) the front wheels Toe In and the stock Tie Rod Arms run out of Adjustment and you can't get the Toe back to anywhere near correct. I saw 16mm of Toe In per side on my car early in the piece and I raced and won like that.
The Triple Adjustable Arms and the Tie Rod Ends from Hard Race fixed that.
Next the Front R/C Roll Centre was way off. Hard Race Ball Joints fixed that by repositioning the R/C. U-Tube replacing Ball Joints in the DC5.
After that a Tegiwa Rack Raiser (UK) is necessary too. A Rack Raiser puts the Toe Arm Angle back close to stock and the Tie Rod Arms get the Bump Steer / Torque Steer working nicely.
All this talk about Angled Arms goes against what I was brought up on how to think about Rod Arm Angles. My heritage dictated flat arms or arms leveled to match Upper and Lower Points was the way to go. I was WRONG with the DC5.
With the DC5 it's about getting the Tie Rod Arms to Camber GAIN the correct way in Bump and Roll.
My specs atm are 3 1/4 Camber with 2.0 Caster with either 0 or 2 degress of Toe Out depending on the Course. My Caster is never changed but the Camber is reduced for a high speed not many corners Course.
For the DC5 Camber is way more important that Caster! Read that again.
In closing the Bump Steer CRITICAL!!!
Getting the Arms to Camber the right way is the secret with the DC5. Don't stuff about. Buy the stuff I used. Get the Bump close to right, put a big hp engine in with C/O's, big Sway Bars, sticky Tires, a bit of Aero and you can rule like I do smashing records along the way. Peace Out.
