Low car + replacement axles + raising diff advice - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

JordanWho · 07-22-2013, 07:11 AM

So last friday I was out drifting and it was all fun and games until I shattered a bearing casing and had to get the car towed home. Good to see I waited seven months for the car and I've very successfully broken it in three months.

It's on BC BR's which are wound quite low and soon to have a lot of negative camber to tuck aggressively offset wheels on the rear.

My question is....

I'm assuming, due to the ride height being so low, additional stress has been put on the axles and coupled with drifting and some hard driving, is the reason why the casing has exploded after such a short time. At this stage I'm looking at replacing the factory axles with THESE axles from the Drive Shaft Shop.

I have no doubt these axles will be strong enough to withstand the cars power, now and in the future, but I want to know if these axles would be able to withstand the stress of low cars due to the angle off the diff being changed so dramatically. I really don't want to wreck a set of DSS axles if they haven't been over engineered very low cars.

Alternatively, has anyone considered or attempted to raise their diff to reduce the angle/stress on the axles?

Current mods for reference.

Work Kiwamis 8.5 front 9.5 rears both wrapped in Achilles
BC BR coils
Racer X fabrication rear upper control arms
Cusco front/rear sway bar
Cusco rear sway bar

Car has no engine/power modifications.

These are old pics for reference to low. If anything it's a little slower now and rear upper control arms aren't installed in these.

Do you really have to ask if your suspension modifications contributed to blowing the axle? Of course they did. I'm sure the whack geometry will blow another axle eventually, it'll just take longer.

I love aggressive offsets just as much as the next, but unless you're going to be running wider fenders, you should probably have appropriate/functional sized wheels and tires.

Unless I'm missing the point of massive camber in the rear for drifting.

PBM is working on subframe and diff inserts to help fix the geometry. Between those and some Stance LCAs, the problem will probably be gone.

Wait it out.

DSS can and will build axles for lowered cars, you just need to supply them with the measurement between the hub and the diff with the suspension compressed (to ride height).

How would lowering the diff fix your issue?? If anything you want to raise it higher. You want the axle as straight as possible at rest, with the car lowered the hub is higher than stock in relation to the diff, so you want the diff higher to flatten the axle. I have no clue how much room there is before you hit the floor of the trunk though.

Which end of the axle did you blow apart? The hub end, or the diff end?

JordanWho · 07-23-2013, 12:16 PM

Yeah my mistake.

Broke on the diff side.

Subscribing to this thread... gone through this twice even with lifting my car up alittle on BC Racing Coilovers... I've had enough with this problem happening. I want to get some more info on the best route to take to lowering this car without running into these problems : /

wparsons · 07-23-2013, 04:46 PM

Keep in mind that as you raise the diff you'll also have to change the angle of it to not totally mess up the pinion angle for the driveshaft.

Rumour has it, that if you go low enough.. :P

New axles arrived this morning. Looks strong as fuck. Will be on tomorrow.

When I asked my tuner about longer rear lower control arms, he mentioned that this causes problems with blowing up CV's and axles popping out, because the longer lower control arms cause the axles to be extended too far out.

I bet your problem has more to do with this than excessive angles.

Subframe/rear diff risers!

What exactly "Broke" here? Pic?
