Interesting solution

This might seem like a dumb question at this point, but why cant you use the factory sensor in the rear diff?

Original speedo is cable driven. He would have to swap e28/e30speedo which i believe are different diameter.

I have the same issue i will most likely save some money and use the stack dash and get rid of other gauges.

With the speedbox converter, I WILL be using the sensor (VSS) in the medium case rear diff.

Well some other good news today, I was able to cut more of the ebrake cable tube out with a die grinder. This gave JUST enough room to fit the 2.5" exhaust tubing over the subframe. Woohoo!

Mock up of over subframe section

That makes sense, I was just thinking it was electrical.

I have maybe 0.5" of clearance each way between the driveshaft, floor and fuel tank connecting hose heat shield.

Ah so you did go above subframe. Good man!

I picked up more welding gas and SS wire. Hoping to get the exhaust fully welded up to just behind axle (minus the vbands I need to order to put before and after subframe). Then it's making up my mind with how to do the rear exit. Standard location? Duals? Center exhaust with splitter?

[Bassboy3313]

Finished up welding the exhaust from downpipe to just after rear subframe. Gotta order materials for the hangers tho.

I also did a thing...

[Jdesign]

Installing a single person hot tub?

[Bassboy3313]

I like your thinking!! But unfortunately no hot tub in the plans. Got the new pan cut and fitted tho.

Sweet! did you make that pan or was it something you bought and trimmed to fit?

nice progress!

[Bassboy3313]

I'm thinking a diffuser like this with twin tip center exhaust. Thoughts? Opinions?

Why not? #becauseracecar

Got my speedo goodies back in the mail today. Should be interesting when I get around to installing it.

Sorry, got busy last night with a few decal orders I needed to get out the door. Not much to show pics of honestly, but I'll still post something later tonight.
