Hi guys,
GREAT forum! Been lurking - every time I google anything about my Civic, the top hits are always here!
Bought a Civic Sport 6-manual new as soon as they hit the dealers lots in December of 2018, fun and economical commuter. The long throws of the transmission bugged me a bit (my other DD is a 2013 Mazda MX-5, and the 6-speed transmission on that is amazing), so a couple of months ago I bought the Boomba Racing short throw adapter that bolts in under the hood. Throws are shorter, but honestly the feel is more rubbery when shifting, so when looking into the Acuity Base Bushings to make that more solid, and doing more reading, I found that if I was going to do all that disassembly, may as well replace the entire shifter with either an SI, or a Type R, either 2016-19, or 2020 with shorter throws.
If I get an SI shifter, could keep the Boomba adapter, but honestly since it makes the shifts rubbery, thinking the smart money is to get a Type R OEM shifter, with the Acuity base bushings.
And as long as I have to remove my battery again and get under the hood to remove the Boomba adapter, may as well replace the shifter cable bushings with the ones from Acuity?
Final question - with the Type R shifter, would it be worthwhile to place an Acuity Centering Spring - or is that overkill or will it make the shifter feel less buttery? (I have driven a Type R that was on the lot at a CarMax - and the shift feel was amazing).
Would love the thought of the forum, thanks!
Gonna post a poll with those 3 choices, as those seem to be the best options from where I am.
