High speed driving

I live in Germany right now. Driving on the autobahn (highway) here is great because there are little speed restrictions. Basically you can drive at a 'safe' speed. I currently drive a 2003 Honda Accord V6, all stock parts.

When driving at around 100mph - 110mph the car seems to float a little and makes me feel uneasy about the handling.

Since my automotive skills would make me a great plumber, I need some input and suggestions as to what kind of modifications I need to do in order to give the car better handling.

I was thinking of maybe lowering the suspension and possibly getting a body kit to make it a little lower as well.

If suspension lowering is what I need, which brands are the best to get for the Accord V6? What parts will I need? Will a body kit make the car more aerodynamic and take away the 'floaty' feeling?

Thanks for any input.

Get a front slipper and a rear diffuser if you can. It will help keep air front getting turbulent under the car. Also yes lowering it will help - divert air over the top instead of under the car.

Most body kits are 100% unfunctional. I would start with the suspension, springs & struts. H&R, Eibach, Neuspeed, Koni are always good. www.tirerack.com

Tein is also a great brand.

I remember driving 130+ on the autobahn back in the '70s! I miss those days. Don't forget to consider brake modifications. Also consider your tire rating. A more stable car might tempt you to go beyond the tire's speed rating.

very true a set of tires a bit of a drop and if you can find wind tunnel tested areo kits they might help but like a lip spoiler would probbly be enough.
dont get one that isn't it could make your car alot worse at speeds.
And good call phoenixtc brake upgrades always good!

Thanks for all the input. You all have been helpful.

i believe that the only bodykit company that does actual wind testing is Mugen. they have bodykits that increase downfoarce but they run about $3000.

Bodykits, perhaps...

But diffusers would actually help him out in his case. Remember, 110mph here on the Autobahn. These things don't cominto play till about 90mph or more, but on the city streets, that's why they are a waste of money, unless you actually go the speeds that they benifit you.

I don't know if there's any sort of wing that might help, I'm thinking probably not though. Again, might normally be considered rice, but at his speeds it could be more safe to have than to not.

As for suspension, I'd suggest thicker front and rear swaybars as well as getting at least a front upper strut tower bar, that usually will stiffen up the steering some, as well as maybe a front lower tiebar or tie brace. A rear strut tower brace might not be a bad idea either. I'm not sure what the conditions of the roads there is (are there cobblestone roads, or are most pretty smooth with few dips and potholes). If so, then the stiffer suspension you can get, the better the car will track the ground at higher speeds. Also upgrading to larger and wider wheels/tires could help some too.

You could also fabricate your own front and rear diffuser. Not too hard, just make sure you use EXTRA pop rivets. I plan on doing this this coming winter with some carbon fiber pieces you can buy online

I own a 2003 accord 4cyl sedan and V-6 coupe here in Canada

I would suggest contacting Honda racers/shops/specialists in Germany. Hi-speed suspension is generally specific to race cars and race environments

ie: the accord comes equipped with shock tower braces but they attach to the frame as opposed to both/each of the shock towers. how do you test stock vs aftermarket when they are different designs??

airflow - as the other posts have stated, few body kits are strong enough or engineered properly enough to affect downforce/side-side stability.

racers and professional shops are IMHO the best bet.
