Here are a few pictures along with the new RENNtech 63 AMG CF Airbox!







Prices at $995 and I have one ready to ship! these are all assembled by hand

 

Looks great James

Are there any differences between the CF boxes for the E/CLS63 vs C63?

What are the prices of the boxes and will it require a different size filter?

 

Looks good! Question though - allegedly MB stiffened up the w204 chassis quite a bit (and frankly, it's not like the w203 was a limp noodle to begin with)... consequently, is there a noticeable improvement in steering response and/or handling precision?

 

Nice looking strut brace! I too am curious if the driving feel is improved noticeably? Geez, it is so easy to spend $1k here, $1k there on this car.

The CF air box looks good too! A little bit more stylish than my CF air box However no front engine cover is included? And price on air box?

 

I have the Performance Package suspension... would this make much of a difference at all?

Not feeling that air box, I like the Brabus and MHP ones better...

 

The stock airbox looks better

 

will there be anything like that for the SL63? or we cant put sth like that on the air suspension?

also will the SL63 be using the same cf airbox? if not, what will be the differences?

thanks!

 

looks nice

 

Sexy brace! Airbox is pretty sweet, too...

 

have the air box on order it has real hp gain As for the brace, If this fits the CLS63 James is in HUGE trouble for not telling me .. Are you kidding? that thing looks SWEET and going on my car. That's a great show piece for any SuperCar It's mine

 

These air box provide a modest 20 hp gain...

Mo they are the same fitment and they will come with new filters, Rick has one on order. The price for the airbox is $2995, but call me and we'll set you up.

 

I wish that strut tower brace would fit the airmatic cars, you know I would just order it and show up at your door with it... hahaah

 

James,
"These air box provide a modest 20 hp gain..."

Was this gain on a stock car, tuned car, tuned with headers? I am interested in another 20hp but thats a bold statement since the other C/F airboxes showed no gains. You or Renntech will have to shed more light on this if you expect someone to shell out $2995 for 20hp like dyno graphs or how the tests were run or what car they were done on? We need more information please.

Thanks,
Keith

its imposible to get dyno numbers from airboxes or air filters,
i dynoed my car with 0 filters and still dint show any power gains.

 

looks great but the price is abit steep.

 

PS: The brace will do NOTHING for a stock suspension. If, and I do mean IF you run LUDICROUS front spring rates, then YES it COULD make a a difference. I will say this, It does LOOK GREAT

Have tried these braces on MANY cars over the years, at autocross/road racing. NONE of them made ANY difference. Sorry guys, but there just ISN'T that much flex going on up there.

See yeah

 

Yeah that’s what I thought... It DOES look great but for $1000 it’s just not worth it at all, you can put that money to good use elsewhere...

 

please more info on the cf airbox!

 

My understanding was the airbox gained about 12 whp on top of the tune. RENN's engineer (Dustin) did a great job on that one.

 

DOODE, that is sikkkkk

 

James, with the addition of the Renntech CF Strut Brace on a Performance Pack C63, how would it affect the car? Stiffer chassis? Less bodyroll?

 

Chalk the strut towers on a normal road car and take it to the track and beat he hell out of it it. Also chalk the other high stress parts of the chassis in the front and you will see massive amounts of flex. You might not feel the car potatochipping but its all bending and flexing away as you flog at it.

The brace wont stop it all but it will help. You need a true roll cage to stop all flex but thats for track cars only.

 

Will this brace fit the C55 as well? It looks as if it might. Let me know.

 

Currently only be tested on the W204's and GLK...
