dude its cool its still stock arms but trust me when i tell you STANCE coilovers are your friend they will drop the car to the point where the frame is on the ground but its a really good coilover to track on or just give the car better stance

Mate, I'm all over ride height, and its effect on roll centre. Dave C got me interested with his posts, and I've been a researcher's wet dream ever since. Looking cool and handling well are almost mutually exclusive with our chassis, unfortunately.
I was interested to see if he had access to some adjustable stuff in the US that we(I) might not know about.

Looks cool mate. Although take note Ben that being that low will handle crap on the track!
Its actually worse on the street
basically at that height, you can still go pretty quick. Like I outlined, I said "its not optimal"
I would roll the guards and correct the camber, roll centres you can put up with, if you can steer well, and bump steer is a bitch, as its hard to be consistant with your driving, the cars is also very "darty", in a bad way.
The other issue with that low at the front is brakes locking up, but its not that bad, only big down hills or if your really pushing hard, I dont know how hard people on here push their own cars, but I push mine VERY HARD on the street.
Apart from big tyre wear, his car might still handle Ok still, the differnce at the track would maybe be 3 secs a lap and a muc more inconsistant lap time, but for a street cruiser.... Who cares •••
Oh and by the way, you have IMO the best coloured soarer

well right now just to let yall know im getting rid of those wheels and moving up to and 18x10 and 18x11 with lower offsets so camber will be added to the rear and front here in texas the roads are all paved so there are no worries except for rail road tracks and pot holes and steep driveways i usually dont drive fast i like my car low and slow i plan on having this car look pretty crazy there will be updates to is starting may of this year

Depends on your tyres spring rates shocks ect.
It isn't a simple thing.
Generally lowering the roll center will allow the car to generate more grip by at the expensive of stability.
If you are tunning a street car or track car you need to take the balance into account and you may be prepaired to loose some grip at the expense of increased high speed stability. Likewise you may need to loose some mid corner grip to acheive better braking so you can go in harder and deeper.
I would suggest that in my experience driving a number of different soarers with different modifications with a reasonably lowered car running stiffer spring rates and shocks to suit even with very sticky tyres you would be fine. (Reasonably lowered means the tyres still have clearence between the gaurd at static ride height.)
Just out of interest sake with I race RC cars I change the roll centers to account for the age of the tyres. I lower it with older tyres to help generate more grip. But with new tyres with a lower roll center the car becomes unstable so you have to raise it. The difference between new a used tyres is massive unlike full scale cars where the difference isn't as bad.
With on road experience with soarers the front cannot be lowered as much as the rear, this is probably due to bump steer ect as Dave indicated as possible issues with very low ride height. The rear does like to be lowered a little more IMO.
If you look at new M3's Audi's ect they are all doing the same, lowering the rear more than the front. Sure it looks gay but at least for those cars it is proven to handel better.
The biggest change I would like to make if it was reasonably possible and it isn't for a street car but might be possible with one of the cars in the track car project section is the move the front wheels closer to the center of the car.
Shorten the wheel base a little will help with front end grip and turn in which is where a stock(ish) soarer is lacking most IMO.

ok the front can go lower but i cant because of my tire size. If i were running a smaller tire in front with more stretch and camber which i already tried i have no problems turning. The front fenders have been pulled out around 2 inches which was the problem when i had the front lower. I raised it because of the sharp metal under the fender that was cutting into the tire when i hit a bump it will be grinded down and the car will sit lower by june or july
