What is the lightest spare? 15" with worn, slick minimum size tire prob a good start.
Replace spare with 100 mi tow on AAA card and can of "fix a Flat"?
Fuel tank 1/2 full max? 11 gal x 6.7lb = 74.3lb
m20 is a peanut sized engine. What is smallest size batt that will do the job?.
Go on a diet? Body weight 170 at 70" so max pot maybe minus 10.
Change diff?
'89 525a already 4.10
'89 525m 3.73, 4.10 is possible.
Chip?
Trade on 535. Good idea but really like feel of lightness of 525.
Alum lower control arms. How much reduction?
2.7 m20 w 2.5 head and TD crank?
Remove engine and install in my 2002. That may be the real deal.
Korman m3 swap into 525. $25,000. Bull s***.
