Hey, welcome to the site. The more the merrier. Give us some specs on your car. List of mods or something. What all did you upgrade when you went with the Zex kit?

As far as the car getting squirelly... do you have any suspension modifications? If not I would suggest lowering your car and getting some stiffer springs. If you have the $$$ get some coilovers. Also a front lip and well designed spoiler will help keep your a$$ on the ground. And for those of you that say spoilers are usless on FWD cars, you're right.... at least until you hit higher speeds. Also make sure your rubber can handle those high speeds. Not to mention if you're going 145 you should have a full roll cage and racing harness. The tib is pretty durable and protects its drivers well, but at 145 even a tank will crush like a tin can. :surprised:

145mph!! Holy geez, You topped your bitch out!!

Best things that will help you? Wider tires, 205 or 215 is all your can fit.

Lower springs will help alot.

Think about getting some winglets, they will help keep you front down by using air flow to your advantage.

Also a lower spoiler to the deck helps.

Spoilers do help FWD, they help keep the read end stable since there is no power to the rear wheels.

The winglets and spoiler does not really have a noticabl affect till about 70+ mph

hey thanks alot . what about dampers. are these any good for downforce?

If you want to use the winglets, look into a diffuser/splitter assy. also with a lower(or no)rear wing as Shadohh suggested. Also look into venting the bonnet(directional vents)to reduce the pressure in the engine bay and to make it work for you.

For the suspension, remember that FWD not only moves weight to the rear of the car on accleration, but also reduces traction at the same time. An LSD would do more to help in this, along with high-speed-stability(lower angle of attack)aerodynamic modification.

Hope that helped a little.

I have never used them, so I cant comment.

KORE has a baddass set of inexpensive coilovers. They're fully race adjustable. The ones in that pic look good, but $749??? :shocked:

Hi,

TnP is discontinued now and TnK took over
that is why it is low cost
The ride quality is really really hard
however they will customize the springs depend on what you want
TnK soft and hard are basically the same thing except the oil pressure is different
any morea questions can be asked at the Q&A at kSpec
i use TnP because i don't mind about ride quality and have bodykit and 17 wheels
hope it helped~

The QUEST Coilovers KORe has remarket have been purchased by Random in the past. And has was no to thrilled with them.

The quality of them just by eye inspection is not here, I have seen this myself. Also, As I understand only one of the adjustments has preset, the others do not. so you would need to get friendly with a shop thatdoes corner balancing, any time you want to play with you coilovers.
