A few parts showed up...

Dont worry the grade 8 bolts are for mock up only. I will be replacing those with alloy steel shoulder bolts later.

The high misalignment rodends are for the outer tierods so that I can eliminate bumpsteer.

I also marked the outer shock tower supports for clearance.

I dialed out almost all of the bumpsteer today. I have zero toe change in droop and .090 toe in during compression. This may help during cornering and ackermann. I run .060 toe out right now at ride height which reduces my ackermann. So during a hard turn the outside would compress and toe in slightly, increasing my ackermann. I will try this setting out on March 2nd at the SCCA event. If I dont like it I will remove one shim and move the outer tie rod up, this will reduce the toe in during bump. I made the spacers tonight and will pick up alloy steel shoulder bolt on monday and bolt eveything together and snap some pictures. I spaced the rodend down so that the center is about 2inches below the bottom of the spindle.

You do a better job with pictures than me so looking forward to those.

Sounds like progress. I know you have some more plans to deal with body roll spill the beans.:D

I am going from 300 lb spring to 400 lb spring in the front. (remember I have a 86% motion ratio instead of 50% like camaros.) This is easier for me right now than adding a bigger sway bar. But a splined sway bar is in my plans for this year. I currently run a solid 1.125. I will end up with a 1.25 hollow bar with aluminum arms.

updates to the TDL:

The trans cooler needs a fan: DONE
Remove local trans temp gauge and move to the dash: DONE
Install 400 lbs/in springs: SPRINGS RECEIVED
Install gauge into the engine oil pan to monitor temp: DONE
Notch and reweld the outer shock tower supports. NOTCHING COMPLETE
Install a breather catch can: 50% COMPLETE
Dial in the steering and remove as much bumpsteer as possible. I ordered high misalignment rod ends. The mustang with a similar set up is down to .015" toe change over 6" of droop. 90% COMPLETE

Hey Bryce, can you explain a little further for us non engineering inclinded individuals? I'm curious about the toe out setting. Do you have to run the .060 toe out at ride height to keep from getting excessive toe in under compression when cornering?

Matt,

I know you get this, so when rob or greg ask you to post a question just tell them to do it themselves... LOL.

I run toe out ar ride height in order to get faster reacting turn in. Since the inside tire is all ready pointed in the direction of the turn. Since I have no toe change under suspension droop the inside toe angle during the turn will not change. Since the outside tire during a turn has less angle than the inside tire (definition of ackerman) the static toe out reduces ackerman. During a turn the outside suspension is under compression, my current bumpsteer setup will induce a little toe in under compression; that should increase ackerman. In theory that would cancel the reduced ackerman due to the static toe out I like to run.

Did that make sense?

Doesnt that make it a little twitchy on the hwy?

Instead of explaining it over and over,you could just SHOW us at Adams! :confused59:

nope, not even with 8:1 steering.
