Looking at the miata tire calculator 285/25 is 0.6% too slow and 305/25 is 0.6% too fast. Not much in it.

Basically a band pass box come in two varieties, 4th order and 6th order. The orders refer to the slope of fall off either side of the tuning frequencies. but both are a box divided into two compartments with the sub firing into the other. A 4th order bandpass box has a sealed sub compartment with a front comparment on it that is vented. Normally the vents are large enough to be able to see a sub but normal round ports can also be used. A 6th order bandpass box has a vented sub compartment and vented front compartment. Bandpass boxes are chosen when you need to tune the response or maximise the output over a chosen frequency range. Generally they are more effcient than a sealed or vented box so produce more bass for a given input. It's the same princaple you would use when firing a sub into a corneer of the boot to maximise it's output (ie boundary gain). You can also tailor the rate at which the efficiency falls off to better minimise sub 20hz output and that over the 80hz (or whatever your chosen level is) crossover point to the front seakers. Also vented boxes are more effcient than sealed boxes.

Thanks, might stick with 285's then. Rolled guards is easy.

Looking to get some Speeddy Cheetah rims in black with a silver lip (pic below) and was hoping to get some confirmation on fitment to the car. I'm looking at the 20x8.5 +30 at the fornt and 20x10 +38 on the back. Can anyone tell me whether these will fit with a 245/30/20 front tire and a 285/25/20 back (or wider, 305/25/20). Thanks

Got a silhouette with charcol interior too. Had mine a bit over a year. Would be a great idea for us to atch up somewhere.

Thanks for that Dyno Junkie

Anyone running a set of these on an FG? BBS CH Black Looking at getting the 19x8 and 19x9's for a G6ET and hoping someone can comment on fitment.

Nice car interested to see what you do with the stereo.

So whats the cost of supply and fit of a Ford LSD? Looking to get one in the next few months.

not sure it qualifies as quiet but xforce have a nice 4" for $2500

That looks hot mate, good work.

So do I, that sound as it does the cylinder cut while changes. Very cool

Timbos' Looks like you may have to start making packs of bulbs for the forums, these seem to be very popular. Now just need to source bulbs for the rear lights and indicators.

Cool, it's always nice to have someone who went before you. Can you tell me where you got your ACC wire from and whether you used the standard speaker cabling (thinking of keeping it to avoide too much interior dismantling).

Anywhere in the boot to do this?
