Nice thing with that rear, since its a domestic, you'll have an *** load of options as far as final drive ratios and aftermarket axels. As well as half the price.

So it makes more sense to have a stronger 8.8 then the mazda..
Do you plan on buying the subframe or making it and selling your own?

TurboR1 Im amazed the stock diff lasted this long and too achieve 10 second runs on it is excellant. I broke my stock diff on a 12 second run a few years ago lol
Kazz 1.5 way has been good to me so far, Im still running stock axles, got some Stillway 300m axles still in my garage waiting to go on, but looking for a way of making CV Joints\Half cups stronger, I may cryo them.

Ray Wilson (PFS) ran 9's on a stock diff all day long. No kazz, no upgraded axles. Just a brace.

any reason why you aren't going with a solid 8.8? or did you just want to stick with a irs style?

The key to that is to set up the clutch to slip and pre load the diff on launches and or higher tire pressures. There's no way he's side stepping the clutch with full lock up(no tire spin) on stock rear and axles and running 9 seconds all day long.

Oh, ok. The way you said it made it sound like he had no problems.

On another note. For all you IRS drag racers... got a question. It seems like you guys mainly drag race your cars, so why not just install a solid rearend like a ford 8.8 or 9" and be done with all this axle/diff breaking BS. Is there a special class or something or are you just out there to prove something? Do tell.

Ernie the case exploded. Pieces of the cover,bolts and the case were all over the track not sure exactly what happened until we take it out but something in the gears prob just let go and shot thru the case. Yea everything is stock R1 in my car axles and all everything, but i guess not anymore. Ive got stock axles for sale now if anyone wants them.
Good call on that. I LOVE my 8.8" rearend.

For me I still drive this on the roads at weekends, we have a lot of small country roads with fast bends and corners here in the uk,nothing like taking a fast sweeper at speed and will be taking it on on circuits as well so defo need to stick to IRS, I want a good all round quick car that can do it all.

I think most of us still drive our cars on the street so it's a waste of time. You also have to get someone competent to install and setup the straight rear and there would be downtime involved. setting it up, testing it etc. The easiest way to go would be the Kaaz and the new axle setup, it will take one day to install a Kaaz and axle setup. If you decide you want something else, it's pretty easy to sell the Kaaz and axle setup as well.

Really? Because your 60 foot says otherwise.....

I think you're the only person I know who's gone slower after a rearend swap.

My previous 8.8 swap was nice to drive on the street and handled alot better than I imagined. I too was caught up with the "Straight axles are only for straight" hype as well.

People still roadrace their straight axle rearends and are still competitive.

That 8.8 straight axle swap was pretty darn easy and could be done in just a day or two. It's the perfect length so it won't need to be shortened or lengthened. Stock FD shocks and coils fit. Just buy two driveside ranger axles from the junkyard. Flip the control arm brackets, fab up some control arms and chassis brackets, get a driveshaft and go.

I ran my 8.8 bone stock, didn't even open up the diff and ran numerous 1.50/10.50 passes... $50 for rearend, $15 for ranger axle, $80 for some rodends, $20 for some tubing, $100 for misc welding, $180 for driveshaft....

Cheap Cheap

Anthony,
I did some research on that 8.8 rear. That **** is NOT cheap! The upgraded axles alone are $2200, plus you still have the buy the subframe, have it fabricated to make it work, then buy the right gears. Not to mention time consuming, it may be alot quicker just to stick with the irs, kazz, axel hub assembly, and gurdle. Either way good luck, but it seems pricy and time consuming, from what I was finding out. Trust me I know about not having your car when ya want it

haha I know what it costs thats why I replied it was pricey when you said it was cheap, thought it was just your bank account and spending power talking compared to mine since you get all the high dolla items like that 1200 dollar boost controller lol.

The swap is going to be over 4k. Need a drive shaft as well and also a new tranny mount since the PPF will be removed. Only thing that is cheap is the gears which are like 185 bucks new everything else is pricey as hell and adds up quick. spending alot of $$ on this piece of crap this year, should have built a stang instead I would be going 9s already at a fraction of the cost lol o well cant turn back now.

I get alot of the stuff i have for free, like that boost controller. Vendors are pretty helpful when you've been at it for as long as I have, lol... So I really don't spend as much as people think I do.
