I have an '03 Miata...great car...love it..however, I would like some
better back support and, of course, more leg room. I have seen many a
thread discussing removal of  seat back foam, removal of the driver
side arm rest, removal of the driver side foot rest. However, I'm not

just changed all the oil to royal purple if that matters.  changed engine
oil 4qts 5w30,  trans, 2 qts 75w90 and differential 2 qts 75w90

"buy it now" price of $175 with a $40 credit for a core. I sent the seller

was parked at work and messed up my bumper, hood and one
of the lights.  I had it repaired, but now the gap

Just today the long process of changing over the engine on my 90 miata
was completed. The crankshaft on the original engine was the short
crank and the keyway had already been filled so rather then replacing
the crank on the engine (which had a little over 200Ks already) I

I'm a new Miata (2001 LS)owner with some questions.  I hear a "chirp" that
seems to be a clutch or transmission issue at about 4000rpm or over.
vehicle hesitates ever so slightly at the same time as the "chirp".  Does
anyone else experience this?
