E21 Project Thread - Part 2

[Daggerty]

Grow a third arm and check power and ground while using it.

[Jeff]

What Lincoln welder do you have?

[Bassboy3313]

Got a good amount of work done this weekend. Got a new welder a few weeks ago, cut the old structure out under car, welded in new metal to strengthen it back up, made dual diff hanger mojts, welded them in, painted it all up and got the subframe/diff torqued down.

[Earl]

Going to push for the picnic?

[Bassboy3313]

Trying to, but won't be rushing anything either. That's when mistakes happen and I don't want to have to do something AGAIN just because I rushed.

[Earl]

Have you gone back over the cooling system? That seems to be the part that always sabotages you coming places=/

[Bassboy3313]

There is still quite a bit I need to check over from previous "rush" jobs. I want to fix the exhaust leak at the manifold, fuel leak at the feed connection point, and definitely look to see how I can redo the lower hose routing. All this on top of finishing up the rear end. Then of course body work and group 2 kit install. Oh and I will need to see if I will have to redo the exhaust or not.

[Earl]

In 4 Gruppe 2 kit!!!!!!

[Bassboy3313]

Motorsport hardware studs installed in rear hubs. CV axle hardware cleaned and installed with a shit ton of locktite. Better not come out again. Rear rotors resurfaced and installed along with calipers. Rear brakes bled. And test fit of new wheels. Guess I didn't account for the negative camber when calculating fitment with flares. Will have to see what is needed after car is on ground.

[Daggerty]

That rear end looks insane. You need some 355s

[B C]

Throw some D's on it

[Bassboy3313]

Yup, just what I thought. Kicking myself for not welding in some camber adjustments when the subframe was out. Also, still notbaure about that wheel gap with the flares. [emoji53]

[Earl]

Probably should find some wheels that fill them out. You'll need some pretty gnarly negative offset and a little more width

[Bassboy3313]

I originally thought these would do the trick. They are 15x9 with -15 offset. I guess I just didn't take the excessive camber into account. I flipped the subframe mounts which brings it higher up into the chassis, helped the camber slightly. I just ordered some camber adjustments to weld in to dial out a little more. If I have to run a small spacer so be it. My motorsport hardware studs have the room for spacers so that wouldn't be an issue.

Damn. Looks like you need 16x12's. What size wheels do other E21's use with that flare setup?

[Bassboy3313]

Yes professional race teams with group 2 e21's use wide ass wheels, but majority of people just run 7-9" wide wheels with spacers. Some I have seen use 16s and others ive seen use even 13s, so its a horse a piece really.

[straight6pwr]

camber adjustment, spacers and some wider rubber? 275s? 285s? the stretchy tire is killin the race car vibe.

those wheels are going to look so nice, it would be a shame to change them.

[Bassboy3313]

I agree, the tire stretch is a little more than I wanted, but there just isn't much out there in a wide performance tire for a 15" wheel without spending a shit ton. Didn't want to break the bank when there is still plenty left to pay for on this car.

225s on a 9" is a quite common setup for autox... slight stretch can help with sidewall deflection as well

Looks will always be subjective though

[KaiserRolls]

Bassface sell the 225s and buy the RS4 245s if you're worried about the look
