Whats the size and back spacing of the wheel if you dont mind me asking?

It's a 15x10 Holeshot. Backspacing is 6.5" but we're using a 1/2" spacer.

The stock wheels look good with et streets

what is the backspacing on the front wheels?
also i know that 5.0 backspacing for the rear is ideal but if its not available how does the 4.5 work for you?
would you have enough room to go with 5.5bs?

Weld RTS. 15x8.25 5.5 bs with ET Streets in 26x10

Yeah i have 15x4 front runners with 1.75" backspace and they sit outside the guards with a 25x4 MT tyre and also hit the caliper :(
still trying to find anyone who makes a rim that fits????????

But i do run a 15x10 wheel with a 26x10 slick

i know what wheels i want but not sure what size to get cause i am not sure what fits

i sectioned and boxed my rear lower control arm at the front edge of it , i was anticipating 5 to 5.5 inch backspace, the front outer edge of the rear lower control arm is the bit that stops decent backspace from happening under the rear of a FC , but in the end i got shitty 4.5 inch backspace . I can show a pic if you wish, the rear guard lip needs rolling or flaring as much as you can too .

the front im sure was 1.75 , it has a 5mm spacer to clear the calliper transfer port, do not machine that bit off :blush: , i can lower my coilovers all the way down with no drama, i also have the camber plates full negative, but it only is 2.5 deg neg anyway :icon_tup:
Sorry for the late reply, my updates aren't coming to my email anymore :scratch:

I have a question and I dont know if this is the correct topic to ask

I have a track prepared FD and I decided to do my first drag event. The track we have here has NOTHING to do with a proper drag strip

It uses glue only for 10-15 meter ( 30-40ft ) and the rest is normal highway tarmak

My setup gives me about 420bhp ( engine ) and I used track day tyres and not proper drag slicks...

My tyres where TOYO R888 size 255-40-17 and my best pass was 12.51 with the first 62ft covered in 2.25 - 2.35 secs. My exit speed was 120mph

So my first mod is to fit mickey tomson ET STREET size 26-10-16 on factory fitted 16'' rims. IS THIS OK??? Are the standard rims wide enough for this tyres? If not how wide do they need to be???

Also at this kind of power ( 420bhp engine ) and ET STREET tyres should I expect prop shafts , drive shafts , rear diff and rear diff case , gearbox etc to start falling to bits , blowing up etc etc

I am only asking because I have to drive 450 miles from and to the track...

Thanks alot

They will be fine. Best thing you could do! The differential will be the next weak link. Mine lasted a few years on et streets. Try to preload the driveline. Use the e brake and slip clutch to stage. This keeps everything tight and less chance of breakage.

Next mod.. Add a pfs diff brace. http://www.pfsupercars.com/Mazda/Drivetrain/

Now that's dedication!!! :icon_tup:

This is a clip of my best run. I did a 12.55 with 2.3 62ft and the opponent did a 1.9 62ft but lost with a 12.9

You can see that the wheel spin in 1st and 2nd gear is UNAXEPTABLE

One last question. Proper drag tyres in size 26-10-15 are popular and easy to find in Greece

On the other hand MT ET street 26-10-16 are vary hard to find. Do you know someone ( shop , friend etc ) that can post these tyres to Greece

thanks again
