The washer is so the lug nut rides on the washer when tightening. This avoids the steel lug nut from marring up the aluminum wheel, but from what I've seen, the washer is rotationally fixed which tells me they're for either protecting the lug nut, or it's a retention device. You'll find that a...

I personally wouldn't be overly concerned with how close to the cones you get. That will come naturally as you get faster.

I can understand the first issue you pointed out, but I don't buy you second reason. I'm aware that the tie rod and control arm are no the same length, but that just means that this issue is present no matter what you do with the suspension, raising the control arm pivot points or not. This...

So perhaps safety wiring them might fix this...

RWD4G63 makes a good point. Without a bearing in there, you're going to see some excessive wear. The only way to prolong it's life is if he cut some grooves inside the bushing to retain some grease, and you are regularly re-greasing it.Additionally, if that busing is aluminum, you'll get some...

And so is adding lowering/performance springs. You guys are already lowering the pivot point for the ball joint and the tie rod end because of your lowered suspension, it seems only natural that one would prefer to raise the inner control arm attachment points and then lower the tie rod end on...

On the first video I noticed you had a bit more room to track out on the exit of a couple turns, but it's likely that bit you lost there you partially made up for with being well positioned for the next turn. Obviously, the less lateral forces the tires have to endure turning the car, the more...

So is your "local racing" not ChampCar? I'm confused by this. With those upgrades you've listed (not sure if those are current or future upgrades), you should be well over the 500 points limit. Do you start with penalty laps, or does your local tech not care that you've got a bunch of "cheaty"...

I've seen a couple tubular k-members for the 1g. Do those not adjust the LCA attachment points to favor a lower ride height?

I'd also like to know the exact capacity for champcar rule requirements... just in case I decide to convert to a fuel cell in the future.

Bummer! Thanks for sharing, though.I'll be sure to avoid.

Fortunate for us in ChampCar, ECU changes don't incur any penalties, so that'll be the first thing. Unfortunately, I have zero experience with ECU tuning so this will be a whole new learning experience. That reminds me... I need to check the ECU to see if it's socketed. I'm hoping I can connect...

Looks like a run of the mill black 1ga, but I'll try to post a few photos, just have to find a decent photo hosing site first.Thanks @1990TSIAWDTALON, I appreciate the input. Already have a new belt installed. So far, I've also done all the filters and fluids, ball joints, tie rod ends, end...

I'm building a 1990 GSX into an endurance road race car. This should be fun!I used to be deep into the E46 M3 community until my M's untimely demise :( Since then, I haven't been involved with any online car community, but I've been helping some racing friends in their pits and it's time I...

I'm also interested to hear/see details on this.
