1978 Malibu Project, 4th times a charm

[64nailhead]

We experienced the same thing with the BJ boots. Bought some aftermarket ones form Southside Machine and they cracked before the car ever made it to the street. I think the standard replacements that come with cheap BJ's at a parts store are more durable. And ones from Moog or the General are much better. I just changed out the factory originals on my MC and they were fine (no cracks.)

Not familiar with having to cut the frame for coilover clearance. I recently swapped in a set of BMR arms on my son's car with QA1 coilovers and there aren't any clearance issues. Please explain.

Glad to see you making progress!!

Overkill is my name

Using the Chicane kit here https://speedtechperformance.com/product/g-body-chicane-brackets/ to go true coilover instead of the hybrid kits that are out there.

Chicane set-up allows for the longer stroke shock & spring combo of a true col-over arrangement.

Little time spent in the garage this weekend on front end mock up. Looks like the drop spindles I picked up years ago will not be cooperating with the 17x9.5 I want to run on the front. These wheels are 5.5" backspacing with a 1/4" spacer to get to this point.




Looks like I'm off to shop for some stock spindles to move the steering arm into a more favorable position and keep on moving with measurements for the new front coilovers.

The issue can get worse (aggressive backspacing vs TRE clearance) if using taller than OE lower BJ's as well so keep that in mind depending on your final objectives.

BTW.... What size tires do you have on those 17's for mock-up?

I'm "trying" to use 275/40/17, same as the rear. Worst case I have to step down to 255/40/17 and ultimate worse case I step down to a 17x8.

Of course all avenues will be taken before I step down in size

Gotcha. I was trying to figure out what the width was looking @ the sidewall 'bulge' in the posted images. 275's was my guess.
