Rigidity imparts a "solid feeling" to the chassis that is perceived by the driver as "well made" and "high quality." Installation of a suitable strut brace when a vehicle is new, helps to maintain the original structural integrity of the vehicle over time and miles. This translates to "still feels new" when the miles rack up. Automotive engineers agree that increasing chassis rigidity imparts quicker and more responsive steering as a result of reduced chassis flex. Almost every racing car has chassis braces added or built in as original equipment for the benefits this rigidity imparts.

An interesting and true story >>>>>>>> following the investigation after the sinking of the Titanic, it was discovered the quality of the steel used in the hull was defective and the thousands of rivets were also substandard. If these materials had been up to standards, the ship would have withstood the glancing impact and would not have sank.

front wheel spacers

as far as wheels spacers for the front. there is a trade off in steering response or feel maybe depending on the person. as the center of the tires moves out from the balljoint you increase scrub. i feel it as a slow down in the transitions (so to speak), you can increase your stability in the front but you can go to far as well, i think. i borrowed some 15x7 zero offset 205s and it stuck like glue but sucked to drive.

SW21Pilot heres the low down on spacers [ and a little on tire profile ]

adding spacers to just the front will lower understeer, hence giving more oversteer

adding spacers to just rear will reduse, and possibly iliminate oversteer [ in most situations ]

adding them to both front and rear as a whole makes the car more stable. and still keeps the stock [ or close to stock ] response.

the problum that you ran into with the tires could souly be based on the profile and width of the tire. [ along with tire pressure ]

when you have a lower profile and a wider tred the tire is stiffer all over. [ sidewall AND tread-patch ] this means that you have a greatly reduced "slip-angle"
[ this means that the tire dosnt give NEAR as much warnnig once it gets to its limits ]

i found this out first hand when i threw a set of TT 300ZX wheels on the back of my 1991 NA. it was WAY too easy to sldie the back end compared to my stock 205s [ which im actuly running 215 ] and it didnt let me know it was about to slide.

all in all you can look at it like this. . .

the lower, wider the tire the less warning it will give to letting go at the limit. BUT it will also let go more smoothly [ in most cases ] and come back softer.

when i go to the track this is what i run and i have NEVER spun out nor have a plowed a corner.

Front = 15mm spacer with the stock 195 / 60 / 14 @ 35psi
Rear = 25mm spacer with 215 / 60 / 14 @ 38psi

it all boils down to how you drive an what workks with your driving style.

minh-take I have to say that spacers do make a difference... I put a 25mm spacer on the rear using stock rims 205/60/14 tires and i have never experienced snap oversteer, and i never spun out. when i switched rims and tires to 225/50/16, i spun out twice... I dunno if it makes any sense. I dunno why I would spin out easier with wider tires, and a lower offset.. the stock rims I understand have a +45 offset, using the 25mm spacer would make the offset +20... but using the 25mm spacer with a +40 offset rim should make the car a lot more stable in the rear with a much lower offset +15mm.. not to mention the wider tires... but I dont know.. all I know is that when I used the spacer on the stock wheels, I could barely get sideways

rocwandrer careful, there are typos in that, for example, the rear spring rate section is messed up.

zenofspeed The use of Wheel Spacers

Increase Front Track: Reduces Understeer.

Increase Rear Track: Increases Understeer.

If you are limited by wheel to coilover contact, wheel spacers can also increase the range of camber adjustment.

I'm not sure about the effect of spacers on snap-oversteer though. I also don't know what characteristics change when you add equivalent track to both front and rear.

Anyone want to add to the changes that wheel spacers can make?

3sgtemr2t ^^jason you are right!! back breaking almost could you list your suspension mod?

I think it's your coilovers the rebound might be kind of slow but if you have aftermarket sways that could be your problem ...I have tockicos and trd spring and they are soft and grip like hell! I have not tried bilstien and ohlins yet so I can not give you an honest judgement ...forget kyb I HATE THEM!
