Sup. Just got a 91 miata as my DD. My track evo is just too much to drive on the streets now.. This car is now my daily commuter and weekly canyon car.

Some things i would like to know, What do u do about the soft top glass "seperating" from the top itself?? Also, im looking into RPF1's and i want to run a 225 tire, so any offset tips, width, rim size ect will be helpful.. What spark plugs do you run if ur seeing alot of high rpms? I run regular NGK's in my track evo so maybe they will be good for the NA? Synthetic or regular oil for a 175k motor that sees lots of high rpms?

I bought this NA less than a week ago and already put 2k miles on it. So far i love driving this little thing, however, this is my first rwd car so i have no idea how to drive it. Gotta get to a local autox event asap, very tricky little car lol

Thanks

Here are some questions for YOU:

Why 225 width tires? How/why are you planning on going past 7200 rpm? Which crank do you have? What suspension do you have?

225 seems like a great size for autox/ spirited driving, and was told thats about the max that people run with this model. this car won't see anything over 7k rpms.. Car is bone stock. Future plans are strictly suspension mods, but not til after i learn how to drive how it sits

Looks like you already did some research and got one pretty terrible post in reply, so here you go.

There are DIYs posted on miata.net regarding replacing window glass, so you may want to check those out. IIRC you're looking at just gluing the thing back into place. You probably won't want to run a 225 wide on a 15x7, so I'd suggest looking into the 949 Racing 6UL. Usable offsets for 15x8 (read: not trendwhore slam idiots) are in the +36 range if you're looking to run a 225. A 225/45/15 wide RS3 on a 15x8 +36 wheel will clear easily all the way around with a slight fender roll on an NA depending on how low you are. Stock height, no roll needed at all. I needed a slight roll and I'm at ~12.5" hub to fender. Run the stock BK7RE NGK plugs (same for wires (NGK), don't cheap out here, seriously). A lot of people run Mobil 1 10w30 synth with good results.

All the questions you asked already have answers either here, miataturbo.net or miata.net. Get used to that search button and welcome.

I run a 225/50/15 crappy all season falken for my daily on my 15x9 6uls but I'm definitely going with some rs3's next time around. Theres a lot of meat on my current setup and don't really have to worry too much about rough roads...even for socal.

Thanks bronto... I frequent alot of forums and didn't want to read 10 pages of opinions... And there's always a knowledgable post whore to answer newb's questions in one shot who knows a thing or two.. Ill be picking up those plugs tomorrow, as well as a nice oil change.. Who knows what the previous owners have done.. And i run 265's on an 8.5" wheel on the evo. So judging by what u say i think i'll run a 15x7.5.. No hella flush love here

Glad I could help! :x:3 I still think 225 is a little much for a daily.
NO!

Oh and swap to coil on plugs instead of doing new wires. Costs about 100 bucks and an afternoon of soldering and goofing off.

No point in running anything less if you can. I have a set of summer wheels and a set of wheels I store the car on, why bother having a third set when 225 RS3s work just fine? (for everything save road noise, they suck for that)

15x9 +36 6ul with 225/45/15 hankook rs3. The 9" width has proven to be faster with the 225/45/15. Its only a slight weight penalty over the x8. Emilio of 949racing and others have data logs to prove it.

If the tops ripping there are tutorials on how to glue it back together. Me personally, I'd just watch the forums for a good condition top to come up for sale. These tops get rather ratty, I'd wager if its coming apart its starting to look ratty too. Or, rip it out for a hard top.

These are the plugs most use, replace your wires while your at it. Our wires have a pretty short life span. Some have reported issues in as little as 30k.

If you have the lifter tick and your car doesn't see cold temps just use 0w30 or something around there. The thinner oil passes through the lifters easier. I use mobile1 full synthetic, but that's because I'm lazy and don't get to my oil changes every 3k.

Check to see if you have a short nose crank shaft or a long nose. The short nose will have 4 slots on the crank pulley, the long nose has 8 slots. If you have a short nose make sure you do not have any crank pulley wobble. If you do make sure you do the "loctite fix" before abusing it at the track. It is well documented on miata.net, just google it.

Miata.net has a wonderful garage section with many service tutorials. Almost everything has been covered there maintenance wise.

Thanks for the info... it has a long nose... and my soft top is brand new... the whole car had been fully restored.. clean black leather inside and a new silver paint job. And a 225 isnt too much tire for a slow car. Autox is mostly 2nd gear and im not teying to slide this thing.. and for the spirited downhill drives.

225 on stock suspension is way too much tire. Weight is a huge factor on any low powered car.

While your Evo may enjoy the rubber noodle sidewall, the carry over of that working here is likely not going to work out in your favor.

It's nice to have that safety net of an RS3 and good suspension in the canyons, but you will learn to drive a lot better on a light weight wheel and a decent all season/summer tire like a Yoko S Drive.

Or he could just be slow. Pretty sure seeing as he already has a dedicated track car he knows how to drive.

OP, buy the 8 or 9" wide 15s and slap the 225 RS3s on. You won't regret it.

S.Drives are terrible tires. I know, I had them.


@OP. Look into 205 star specs on a 8 inch wheels; or 225 rs3s on a 9.

Pretty sure this is the car.


I happen to enjoy the S drive for daily. They are very predictable and a great compromise between grip and wear.

I run 195/50 @ R package bilsteins with little to no problems the majority of the time in the mountains.

Since he is in So Cal, I know the mountains he drives and it would take him half a run to warm up those RS3's and he would be replacing them every other month.

yup, thats my car lol. Well im learning to drive it on the 185/60 non brand name 10 year old all seasons.. they are beyond slippery. I go thru tires monthly in the evo, i can care less about tire life.. And i would be putting 225 AD08's on it.. But u guys actually just turned me into wanting a 215 actually.. But im not doing ANYTHING til i learn how to drive it on shitty tires first.. Judging by tonights run, i say it will take me 2 months to get a solid pace down

or... you could do a track day or auto-x and not slide off a cliff?


unless you did a night time track or auto-x event, disregard the first statement.
