i asked before but ill ask again, since there is much similarity between the 05 STI and our svx in the lines of wheels brakes etc, will we be able to swap the STI axles so we can handle more power than our stock units or are they weaker/don't fit/same ones?

Aren't the FWD SVX axles heavier than the AWD? And could the AWD guys swop out their axles for the FWD ones to handle more power?

TomsSVX · #**213** 12-02-2004, 03:36 PM

sure, the front axles that is, what about the rears? aren't they different?anyway, i would imagine that the STI axles can hold a good amount of power. Also, the fwd are not as heavy as they should be, cuz mine are less than a year old and seem to be crapping the bucket already. Thats why i am intirested in STI axles, although buy 6 of them is gonna put a hurt on my wallet.

BTW mike are u comming to the Jersey Shore meet on the 18th? hope to see u there.

However, the stock components will do just fine if the car is driven in a civilized manner. Even 1/4 mile racing will be fine...

I remember Harry (newsvx) telling me a story at his place about a guy with an upgraded S/C 5.0 Mustang who was racing at Summit Point. He was still on his stock brakes, and after 3-4 laps his stock system just over-heated and failed. Won't go into details but the guy died instantly in the wreck...

Yikes! That is terrible.

I take it he probably started boiling his brake fluid?

Someone pointed out (I think Porter) that the SVX axles are more stout than the WRX axles. I don't think there should be any worries with snapping OEM SVX axles.

Mychailo,
Come on, spin the numbers for us

What's the effective torsional loading prior to a spiral fracture for the front axles? What's your guess as to the material used for the axles (some variant of chrome moly?).

No slicks here - just need two strong rebuilt front axles...

Eventually, I'll want to replace the rear axles as well as the CV and Ball joints. Got to keep my car in top shape for racing...

It was a combination of many things - probably brake fluid boiling coupled with super hot brakes - but at the end of the long straight on Summit there are three run-off areas (one behind the other) to slow a car down if it went off the track. He went through all three and his car was a mangled mess when they finally got to him. He must have been doing over 120mph when he left the track...

My younger brother, Michael Krynock, did 160 mph into hay bales, on a motorcycle while racing at some pro track, I think in his now home state of CA.

He got to go for a ride in a Life Flight helicopter.....

He's still racing.

Very Lucky.

Mychailo,

N/mm2 or lb/in2 ? (are you using (16M)/(pie d3)?)

-Bill

I think the Moment was about 12 midnight. :-))))))

I wonder if upgraded axels for a wrx would be the right lenght for a SVX, or be close enough?
