What'd you do to your car this week/weekend?

Tophat nuts supposedly from all my reading I think

siren676 · Post by **siren676** » Sat Aug 04, 2012 9:56 pm

Just rechecked them and all of them are home/didnt move when leant on. Might just have to borrow some bags of cement and see if leaving some weight in it helps.

If you have undone one of the pivot bolts for the suspension arms, it is best just to nip up the bolts/nuts, lower the car and drive it round the block and then, while it is still on the ground, torque up the pivot bolts.

If you can't get at the bolts to torque them, put the jack under the bottom arm and drop the wheel off. Be careful when you do this as the car will not be on axle stands.

The bushes need to have settled and be under load when the final torque is applied to the pivots.

I haven't heard of it being necessary for the top hat.

There you go, knew it was something to do with bolts.

Lowering springs will take a couple of weeks to settle to their actual height if you buy them brand new.
Also - MX5's vary in height depending on production year and spec etc, so from what I gather its fairly hard to gauge an actual drop when buying lowering springs.
It's better for them to give you a final hub to fender height rather than a total amount of drop.

Luckily 92' was the lowest year

Furai · Post by **Furai** » Sun Aug 05, 2012 5:01 pm

Also off the Tein site, It says S-Tech have a drop of up to 45mm depending on chassis and spring kit.

The actual specs for the NA6CE Springs is.
MAZDA MIATA
NA6C 90-98 STECH SKM64-AUB00
F 4.2/235
R 3/168
F -29
R -19

Depends which tein site you go on. This is what it says about the s techs on the uk site

MX-5
NA6CE/NA8C
90-98
S.TECH
SKM38-AVB00
-45 front -40 rear

Really considering getting some sort of coilovers. Was told to get some of theses by a mate on a toyota starlet forum

What part number is on your box/springs?

Rates look real low on those, Not much above standard. Yours looks more like the 29/19 drop which is stiffer than stock. How does it feel?

siren676 · Post by **siren676** » Sun Aug 05, 2012 5:52 pm

They feel a lot stiffer than stock, seems a little more tail happy now although that may be because i havent got an alignment yet

Will check which number is on my box

I'm not sure how you are avoiding cert with this.

That's what the cert threshold guide says - they are height adjustable, whether its circlip, sleeve or spring perch.......

siren676 · Post by **siren676** » Sun Aug 05, 2012 6:00 pm

Ok so my springs are none of the above part numbers. Box says they are part number SKM38-S1B00

Bwarp · Post by **Bwarp** » Sun Aug 05, 2012 6:02 pm

searching part number on google brings up this:
Tein S-Tech Springs (Soft) for Mazda NA8C
for SKM38-S1B00

siren676 · Post by **siren676** » Sun Aug 05, 2012 6:04 pm

first hit on google brings up this site stating that the drop is 40mm

Bwarp · Post by **Bwarp** » Sun Aug 05, 2012 6:06 pm

is yours NA8C or NA6C?

siren676 · Post by **siren676** » Sun Aug 05, 2012 6:09 pm

NA6C, thought there wasnt any difference aside from slightly more weight at the front from the engine

Because like Konis they are OE Height adjustable?

The thing is no one looks at it, you cant really tell and as long as I dont go under 100mm no one will look.(Not that I plan to)

It was enough to warrant a different chassis number. You'll probably have better results with parts for an NA6C would be my guess

Pretty sure OE means Original Equipment from the manufacturer of the car... My Cuscos are height adjustable, but I still need cert..? By that logic, perch adjustable bilsteins should be certed too. Whether people are going to look or not, (or whether you're just not gonna get cert) they still technically require a cert... right?

It is a rather general statement, The height cant be adjusted unless you fully rebuild the shock(Take of spring and pull out of car to move seat) which is the same with springs, springs make the car height adjustable but changing them but that is allowed?

Maybe its stated as height adjustable from factory(The shocks) which Bilsteins arent?

well i spent my weekend wworking on the bloody skyline... Installed the GPS tracker, and put the sub and amp in...brother in law came to pick it up and i started to show him how it all worked when the sub stopped working! FAAAAAAAAARRRRRRRRK.
We didnt have time to fault find it. i think its the brand new amp.
really great huh "heres your new $1000 stereo, sorry it doesnt work.".
car has gone back to aucks less the amp.

Yeah good point, im starting to consider just getting a refund on the current springs and going for some coilovers instead

wait, aren't the adjusters a step where the bottom spring perch sits on the outer shock body? isn't that what adjusts height? didnt think it was an internals thing. sounds fairly extreme, and would end up that the springs are super super compressed at the lowest setting?

Got a diagram of how they're adjusted?

What'd you do to your car this week/weekend?
