Hey,

Just been watching some videos on the new R56 Challenge Car... and Ive been trying to find out just what sort of modifications they have on them but I literally cant find a single thing!? Is it all a big secret or something?

Does anyone know?

 

i would assume practically everything on the car is modified or completely different.

 

It's the same specs as the factory JCW car isn't it? Except it has a few more goodies for racing, like the full cage and stripped interior, etc. Oh...and those awesome built in air jacks

Here is a link to what is on the Stage 2 JCW car in case you haven't seen it...

Nah....I know they don't run the JCW suspension or the JCW brakes from the factory JCW kit. The coilovers come from KW and the BBK is from AP Racing with some ducting for cooling.

 

Are those KW V.3?

 

They have fender liners on a race car??

 

I'm not sure?

Here's a pic of the engine bay. Pretty simple and stock looking from the outside. Notice though, that they went ahead and beefed up the JCW strut tower base plates....might have felt that they needed a little extra strength for the track use?

you must not have driven many of the road tracks, gummy tires, 100+mph, no matter how clean & smooth it might appear from a distance there's always plenty of rocks & debris getting thrown up and beating the crap out of bodywork from inside the fenderwells, shielding &/or fenderliners are great if you've got the room

I would expect the Mini Challenge cars to have some preset engine rules & a standard chassis; looks like brakes & suspension are open. It's surprisingly difficult to find any real details/tech on the series.

Interesting pics Rally!

I'd like to know where they got their wheel studs. It's curious to see a normal part number on the KW coilovers. I wonder what that heat shield is for behind the coilover?

I see the compressor inlet tube from the airbox is different than stock, however the turbo itself looks identical to the standard R56 MCS.

 

Much like the spec miata class, you'll notice that some of the engine parts have tags and a tie through them to make sure no one is going in and modifying it to get the upper hand in the engine bay.

I wonder if JCW realized how stupid the 14x1.25 was and went ahead and re-drilled the hub to something normal

The heat shield by the coilover had me really confused too...I can't figure out what it could be for

 

This link mentions that the KW's are both "rebound and inbound" adjustable which would mean they are V3's or some custom race application

They also obviously run some type of camber plates up front as most of them appear to have 2-3 degrees of negative camber atleast

I think the heatshield is to prevent the ABS wire to melt..

I am interested to see how these are modified. From what I have seen, the exhaust may be changed but nothing else appears to be switched. Is it possible that the mini challenge only allows the exhaust to be changed, followed by suspension and brakes? Just a thought...

 

Well, in comparison the "consumer" JCW tower brace does look like a wimpy attachment.

 

Melt from what, the brake rotor? It's an awfully large heat shield for a small wire that could've been easily shielded with a small diameter nomex sheath.

Also of note in the suspension pic; you can see the rotor hat has a very thick mounting face; a built-in spacer just like what TSW did for their BBK, only thicker.

 

Stupid question probably... but does anyone know the contact details of any one from Mini Challenge... might be worth asking them?

 

I wonder what their final offset is and whether they've staggered the front to be wider. It looks like the offset is pretty low....even with so much negative camber, the tops of the tires are right at the arches up front.

 

mini says they are the same rims from the factory jcw but those don't look 48mm offset like all of mini's 17's unless they added spacers for the brakes or they are secretly 7.5 inch wide just for the challenge cars... but who knows? but those borbets and r90 wheels for our humble street cars just need a more aggressive offset imo.

 

Anybody help me out with part no's for this strut brace and the turbo inlet pipe?.

TIA.

 

In the German Mini Challenge, they use the KW 2-Way, not the V2 or V3 or Clubsport.
In the UK Mini Challenge, they use Bilstein. Much better! Althought the KW is a very good piece of suspension!
In both Challenges, they use AP Racing brakes.
In the German Challenge, they use 17" rims, whereas in the UK's 16".

Here you have the main differences.

 

ı need strut brace like thıs..where can ı get it from?????

 

mcs_jcw...why do you say that the bilstein's are better?

I think that the KW's aren't V2s or V3s, i think they might be the KW "Race" suspension.

Also, does anyone know what the difference between the Stage II Factory JCW exhaust and the Challenge exhaust is?

 

drooling.. =p

 

I think in English is called Piston Rod, not quite sure, of the strut is thicker than that of the KWs. The suspension that are used in the Mini Challenge is the 2-Way Adjustable KW model.
I've been asking myself that but after being in the UK watching the Mini Challenge I think they use a race catalyst. It's what I can tell you from what I've seen.

 

So the bilstein's are more durable then. Doesn't necessarily mean that it performs any better tho...

I did some research and i can confirm that they do use the KW 2-Ways.

So are you saying the exhaust is identical apart from the catalyst?
