Good write up!

So many people poo-poo on Honda's choice for going with MacPherson struts instead of the old A-arm suspension... I don't see anything wrong with MacPherson struts, and evidently, neither does BMW or Porsche!

One thing MacPherson struts do to improve handing is, by nature of their packaging advantage, is allow carmakers to place the wheels closer to the front and rear resulting in less overhang. Overhang is the difference between overall length and the wheelbase of a car (the distance between front and real axles).

Obviously, long wheelbase/short overall length cars have a handling advantage over shorter wheelbase cars of the same length. Pushing the wheel closer to the front of the car also allows for quicker steering transition and a more accurate feel.

one thing you're forgetting is that almost all of those cars are RWD or AWD. The Si is FWD with struts...thats why its crappier.

The Mini is FWD, as is the Mazdaspeed Protege (not on that
list, but a lot of people have said it is comparable, if not better,
than the ITR in terms of handling), which also uses MacPherson
struts.

Very cool write up - I never was too clear on the differences
in these suspension...

Those cars come better equiped for "handling" tests

i.e. tires

Number 8 (mp3, Mazdaspeed with out the turbo) is the predecessor to the Mazdaspeed.

I agree Dunrick, if our cars came equipped with better tires our handling and braking would drastically improve and the car would have had much better reviews.

A+

I give you an A+ on this write up. Well thought out and well researched. Any suspension can be great. You have to figure the geometry also. It is all in the placement of the strut and the spring of how good it will hold the vehicle and absorb shock. The same spring will create two different levels of damping on a 2 different cars. Millimeters make huge differences on full set up cars like Indicars. The adjustment screws for the front spoilers move like 1/2 millimiter incriments per full turn if i remember right.

One single change on a car can make a regular car ride on rails.

I told you your name is getting popular...
Surprise, awsome hands down right up. Damn good job. I however have to move this to suspension, since that's what it deals with, hope no one minds...I'll also sticky this :)

subaru sti wrc car:
Suspension Front MacPherson strut

Suspension Rear MacPherson strut with longitudinal and transverse link

peugot 206 wrc car:
Front : pseudo McPherson
Rear : pseudo McPherson

skoda fabia wrc car:
Suspensions
McPherson, front and rear

lets break the double wishbone myth a little more

Nice write up. This surely cleared a lot of misunderstandings I had with the suspension.

To go into why honda put a mac pherson strut in the front rather than double wishbone would be long and technical. To make a long story short, Honda originally designed the new civics with double wishbone front and rear. The problem with that was that honda was unable to recieve a 5 star safety rating from side impact collision with it so they went to the mac pherson strut. Ask any honda mechanic.

that is true. I hate our bump steer with this new suspension.

Ok...Hate me if you must,
But one of the tings that attracted me to the civic, no matter which one you bought, was the wishbone suspension.
I understand the need for macphersons..
but that doesnt mnean i have to like it
GOSH DARN IT:mad: ..
just call me old school

yeah, I get ya man. There are days I hate this suspension in the front. It feels like a truck when I hit a few bumps while turning. :mad: I'd much rather have the double wishbone
