XelderX's BG FSP Build
- Thread starter xelderx
- Start date
It's a knock off ebay header for a Probe. The EGR would need to be relocated for fitment on the Proteges, but I don't need EGR with the Megasquirt so I'll just remove it. The flex pipe and everything after it also needs to be replaced since it's 2" diameter and I want 2.5". Racing Mazda used to take these or the OBX version of it and modify it to fit the Protege. Racing Mazda doesn't have them anymore because OBX doesn't have any either.
Here is the endlink setup that I hope will work. The original design was for a single endlink that went through the control arm connecting it to the stock sway above and the ST sway below. With the BJ struts I was able to separate the two swaybars so they can operate independently.
It's a proven setup and was cheap. All of this came off Will Kalman's STS Escort GT that also trophied in FSP in 2006. It's a Suspension Techniques front bar. I'm not sure there are any alternatives for the front swaybar on a BG chassis. I would be open to trying something else, but I'm pretty confident with this setup since it already has a bunch of National trophies.
Yea. When the ST bar is usually installed on the BG chassis there is one long endlink that connects the stock sway bar to the control arm and then continues down to the ST bar. Will said it worked OK, but he was worried about it binding because the swaybars move in a completely different plane than the control arms and it is all bolted together with the only compliance being the poly bushings on the endlinks. Now the upper swaybar and strut move freely with the hiem joint endlinks.
We'll see. Attaching the stock swaybar to the strut should increase it's effectiveness making it feel stiffer than with the stock endlink to the control arm. I might be able to take a little spring out of the front because of this. It also allows me to unhook the ST bar for testing without unhooking the stock bar.

I know there are many ways to skin a cat, but 600lb fronts, stock front swaybar at a 1-1 motion ratio with the wheel AND another swaybar at (what looks like) a .5-1 motion ratio sounds like a crapton of non-compliant front wheelrate.
I have seen Wills car run and it did seem (outwardly) to work, but damn homie!
On a heavier car (probably more nose heavy as well because of the turbo) Ive pulled out some front wheel rate to get a softer setup and more compliance.

I've been thinking about that and I will be doing some testing around that very thing. The first test will be to simply remove the ST front bar and run just the stock bar at 1:1. If that seems to work better I'll try reducing the front springrate and reattaching the ST bar. The real unknown in the whole setup will be the staggered tires and how that affects the overall balance. Believe me, this will probably not be the final suspension setup on the car. There will be quite a bit of tweaking done. At least I have all the possible pieces in place so that changes will be fast without having to wait on parts.

I wont muck up your build thread with my blitherings, but if youd like to look at a setup of another old-school strut mazda of @ the same vintage, send me a PM. Its a heavier, more powerful car but its using a staggered setup (275x10.5"/ 225x9") and by blind luck or design works damn well.
Who knows, between Wills setup, your old setup and if you are interested..my setup youll have enough ammunition to make a killer setup for your car........or confuse the hell out of yourself.

Not much to update at the moment. I've been working on another project, but I did manage to get the front brake rotors done. I'm happy with the way they turned out. These are Wearever blanks that I drilled and then turned down to .010" over minimum. They started out at 11.3 lbs each and they are now 9.3 lbs.
The Megasquirt and all the associated wiring should be here in a few days along with what I hope is the correct radiator. Next week should be a good one.

Keep an eye out for how this turns out. I have nothing against my fellow ST* bretheren....but Im not really liking the whole "lets slip some rules into SP from the not-really-well-thought-out-rules from ST" direction. This makes two attempts at an "equality" rule masquerading as a weight/safety rule.

yeah, honestly I'd be more of a fan of a few ST take backs to line things up, why add more s*** to spend money on?
I've been keeping my eye on that since it started. That is one of the reasons I haven't drilled out the hats yet. I have a hunch that drilled rotors will still be allowed in SP but they will not allow you to modify the rotors outside of the actual braking surface.
