So i have a 2007 mini cooper non-S looking into either the sprint booster 2 or the D1 Spec .. which is better do they even makeke a D1 spec for a 2007 r56 mini coop hatchback on their site it only listed the clubman alittle help would be appreciated... think im going to get a DDM CAI unless the new Aem would work better but heard the air gets a little hotter.. as far as suspension parts think I'll go with the Hotchkis 25.5 mm rear sway bar any thoughts and suggestions i would appreciate ..i know its an automatic non s but the handling could be better in cornering .the throttle response could be alot better. And a cai would help it breathe a little better with a tiny bit of power increase...thanx all

 

I have the D1 on my R53 and love it. It has a lot more adjustability than the Sprint Booster. I adjust mine on every drive. It is a lot of fun going from economy to sport and feeling the difference in throttle response. I have the Hotchkis Sport 25.5 on order so,I can't tell you much about it yet. There are several write ups on it and that is why I went with it. As far as the CAIs I'm running an Alta so I have no info there for you. You will notice more performance with your naturally aspirated engine than we do with our forced air engines. I have had at least 5 different CAIs on different naturally aspirated engines and the smaller the engine the more you noticed the performance gain.

 

so im guessing you either have a turbo or supercharged but you said i should get more out of a naturally aspirated engine and i heard the DDM was really good its closed off and looks almost stock and its a cai. Im also guessing the D1as far as throttle response.and last but not least th Hotchkiss rear sway bar which i believe is lighter and thicker but hollow but everyone says its the best so ..one question on the D1 on the sight i seen one listed for an 07 R56 clubman but nothing for the hatchback dont know if that would be the proper one or not unless u can leave me a link on where to get it for the best price plus be the right one for the car plus any links for the other parts would be appreciated.. thanx alot...
