e30 Trunk Badge Placement

 If you have removed your trunk badges and want to make sure you reinstall them in the correct position use the measurements above.

I have a 325i so I placed tape on the trunk as a guide using these measurements.

From the end of the '5' to the edge of the trunk on the side: 62mm

From the bottom of the trunk up to the bottom of the badge: 19mm

From the '5' to the 'i': 18mm

I used this double sided foam tape and has held great.

Rebuilding the Girling brakes on my e30

These brakes looked like piles of poop. I really wanted to have them powder coated but unfortunately that isn't in the budget so I'm going to try Dupli-Color caliper paint. 

I took the calipers apart and pulled all the seals.

I used a wire wheel to get all the rust off. I masked off the piston chamber and seal seats and then used high-temp primer and Dupli-Color brake caliper paint. 

I found replacement seal kits and also replaced the piston above that has corrosion on it.

Here is the final product. 

After taking the photo I realized I should go ahead and replace the bleeder screws too.

Parts I Used

• Front Brake Seals - Amazon
• Rear Brake Seals - Amazon
• Front Piston - Rock Auto
• High Temp Primer - Amazon
• Caliper Paint - Amazon
• Bleeder Screws - Amazon

Progress on the e30 engine bay

 

I've removed the front of the car to give me easy access to the engine bay. My plan is to replace all the seals and gaskets in the engine except for the rear main seal which doesn't appear to be leaking.

In the picture it's obvious there was a coolant leak from the water pump. Lots of other leaks including the oil filter housing and the power steering fluid is leaking from somewhere.

 This is where my e30 project begins. Just brought it home and parked it in the driveway.
