I want to run some ET's at the drags . What r suggestions to beef up driveline so I don't break everything?

depends on power

if manual

clutch and tailshaft if putting out reasonable power

if auto

flexplate zf input shaft and tailshaft.

Note the stock zf's have a few issues shifting into 4th on those running 450 ish rwkw (or about 130+ mph) - seen it happen half a dozen times last fortnight at willowbank

driveshafts can also be a drama when running bigger power.

ZF's also refuse to shift to 4th at WOT on lower powered cars if they are just worn out like mine was (320 odd rwkw / 120mph)

Who is doing tailshafts in Brisbane ? What r they worth ? It's an auto with 325 and rest of upgrades after June 30, so I need something hard to break, it's a daily that is used for work so reliability is a must Cheers

Is the ZF input shaft a slip out slip in installation or is there more to it
