Front hub differences


Recommended Posts

I have some V7 front hubs and some GC8 hubs (off a WRX of some sort, not sure model, but would have had 4 pots).

 

They look similar, but not the same... Pic below, the two without backing plates are from GC8:

Does anyone know what the real difference is, from what I can recall the GC8 CV/axle looks a fair bit smaller, but I don't have any GC8 bits to compare to know for sure? Are they backwards/forwards compatible etc?

looks like the ABS sensor hole on the GC8 hubs, the ones without backing plates don't appear to have the same mount hole.
They changed to a tone wheel style with v5 onward iirc
If you measure the spline diameter, Then you'll have a better idea of compatibility.

They have the same spline count, I was able to drop a GDB axle into them both and they have the same count (funnily enough it was a rear axle, so that confirms all 4 corners have the same spline count), but definitely the outside shape of the hub is quite different. Not sure if that means you can put GC8 axles in there or not?

Nah I haven't broken any axles for many years now. I only broke my front axles once (both at the same time!)... that was with a 7000rpm side-step launch on warm slicks! I wont do that again!!!!!

Yeah the V7-8 ones are massive, then they go smaller again in the later model ones from memory (GR/GV)

      Afternoon team,
      im new to the group first time posting. Im hoping some body can help me get my launch control all dialled in on my link g4x. Ive had the computer and car all tuned from chris at prestige awesome knowlegable guy super happy with the results but now im wanting to get my launch/anti lag all dialled in. Ive been reading multiple different forums etc all with different conflicking information which has made me nervious with what do i listen to this or that if you get what i mean. Now ive started to make myself familiar with my PClink software etc the past few weeks and im eager to learn how to do minor setups or tweaks etc so im not relieing on my tuner so much and obviously saving myself abit hurt in the back pocket. 
      Now back to the question at hand.... Im wondering if theres and one who could please share there knowledge and wisdom with setting all my values, timing, fuel etc when i have launch control armed and engaged, or even a launch tune file they can possibly send me to load onto my tune. Ive figured out the setup of my digital inputs turning launch control on etc and its obvisously on its pre set factory settings. It engages but doesnt sound the greatest or as angry as it should i feel. Hence reaching out to you good buggers. 
       
      Cheers in advance for any info and help yous maybe able to give me.
       
      Cheers Shaun
