Taken from another website, the seller is claiming that the Fix-It is used in Rally Cross at up to 650 BHP

But would rally-crossers not be using straight cut/dog boxes?

Would these be new/updated versions of the original Fix-It gear-kit, or EXACTLY the same as you sell?

"This gear kit is rated and has been tested to 650BHP in European rally cross"

Also "Coming soon with be a heavy duty front and rear diff package"....are these Fix-It too?

I personally would not use this gear kit in it's current format on a Rally-cross car, as:
1. It is syncromesh engagement, so not very speedy through the gears, and;
2. It still uses a standard first gear / input shaft (soon to be replaced in the next few months), which would not be good enough to continually launch on and given how critical the launch is in rally-cross, I can't see why you would run that risk.

 

Mike: depends on how you launch the car, the kit should be fine, just look at fredriks car, 750brake engine, the gear-kit holds just fine...
But yes the 1.gear is the week point in theeese kits.
I have had mine for almost 2 years now, never broke it, never had any problems with it, and always launching hard with it, and know a few more that realy uses it, and no problems there...

 

Well its all good cant wait to have a launch with mine lol When are the first gears ready mike and what about the input shaft??

cheers nige

 

Give it to Big Nige to test His launch's in his old Escort Cosworth were fooking impressive

 

dont u think fredriks car at 750brake is gunna be a good enuf test??he gets 10 second quarters dont he lol

 

I was saying to Martin about the standard first gear in mine mike and he said he doesn't think it will be a problem at all. He asked how many people had ever broken a first gear.... its always second or third in the MT75 boxes isn't it?

 

isnt the input shaft the weakest bit??

 

Is the Fix-It shot-peened and polished as standard?

Whatever.............I will be faithfull to Quaife - proper designer name with MotorSport pedigree

 

And how many times has it broke doug ? I spose proper motorsport stuff is allways in the workshop lol No not shot peened and polished as standard on the fix its

 

Sold my Quaife after it broke for the THIRD time! I think for around 500bhp they are fine though...

and no FIXIT is not peened and polished as standard.

 

ECOSNIGE

It's called routine maintainence

Anyway, what gearbox are you using?

 

Doug is set in his ways. Not that this is a bad thing.
But he still uses vinyl and valves on his hifi

 

He has a Fixit! and routine matainence MY ARSE!!!! no one likes spending 3k a year on gearbox repairs for limited mileage 20k ROAD CAR

 

Lee, my car is worth a bit more than 20K

Then again, maybe it is'nt

 

Fredrick has broken the first gear on a few occasions , so when racing in Rally-cross where the launch is so critical, I would not want to be using a Fixit kit. On a £100k, 650bhp Rallycross car, I personally don't think a £3k gearkit is suitable . If it was my team, I would be spending £10-20k on sequential dog box, specifically designed for such abuse.

Regarding the input shaft, this is also still standard in the Fixit kit, and again is a weak link when it comes to launching. Once this and the first gear are replaced (which as I said is all being done over the next few months), then the gearkit WILL be bullet proof. However, it will still be syncromesh change, which looses 0.5s with each gearchange on a shonky MT75 . Not what you want for a race car.

So IMO, until the first gear / input shaft is replaced with the upgraded Fixit items, full bore (500+bhp) standing starts should be lifed to single figures before stripping the box down and replacing the first gear / input shaft with another set of shot-peened and polished standard items - before they fail catastrophically. Otherwise you have potentially scrapped £3k (or however much of the rest of the gearkit first takes with it .

Sorry if I sound over-cautious, but that is just the way I am, as not everyone has the funds to flush £3k down the tube just because of something they read on the internet .

 

Mike did I ever tell you I got a reply from zero shift. They said a box would be available for the cossie 4x4 sometime (this year) iirc at circa 15k so unlikely to be within the reach of almost everyone road cossie owner I should think

 

Mike, that is a very honest answer from someone that sells the things

That other discription (at the top of the page in RED) would lead the buyer into thinking that the Fix-It is indistructable (spl).

I actually doubt very much that any competitive rally cross cars are fitted with an H pattern syncro MT75 gearbox.........hence the post

 

Ironically doug, for someone like yourself who doesnt launch but likes to enjoy the torque in the higher gears, the Fixit is probably the perfect solution, should think it would last pretty much forever on your car!

 

All the high power front running Cossie cars I've seen at rallycross events have used sequential gearboxes as they have to try and beat ex-WRC cars on the launch!

 

LOL doug i am running a fix it mate ranj's old box brand new all polished and peened with all new centre diff etc all new parts lol.I was warned off of quafe by your experiance actually lol
