Hi guys,

My car has stock MR Bilstein Struts with Swift Spec-R MR springs.

Spring rates are as follows:

Swift Sports MR: F: 179 (helper section) 269 (main rate), R: 157 (helper section) 314 (main rate). -1.4, -0.66 drop.

My questions is, since I'm doing my clutch, what front and rear sway bar combo do you guys recommend? The car will spend most of it's time on the street but will be tracked occasionally.

I am also installing a Whiteline Roll-Centre Adjustment Kit when I do the clutch so please take that into consideration.

I've been offered cheap Whiteline 27mm front and 22m adjustable bars, will these do or is the rear bar not stiff enough?

Edit: I'm running stock 17's with 235 (92.5in) tyres if it makes a difference.

Thanks guys.

Swift makes a match set for their springs.

I was on the Swift Sports at the time ^^

Whiteline 26mm front and 22mm rear is a good combo also. 24mm can be used. Going too big on the rear bar has poor results on the Evo. So many do it and then get "tri-pod mode". Too large of a bar causes the rear tires to lift in hard cornering. Evo performs best with all 4 wheels on the ground.

Thanks Smike, good advice as always.

Would you say that an adjustable 27mm Whiteline front bar will do?

27mm with 3 way adjustments? Do you know what their spec are for each position?

I don't think Whiteline makes a 26mm front swaybar. They do for EVO X.

The 26mm front 24mm rear Whiteline combo is great.

Yeah, what I thought too. Don't know if they get a secret stock we don't over there.

My bad, just found out that the front bar is actually 26mm.

What would be the difference between a 22mm and 24mm rear swaybar?

2mm.

But seriously, Google around for a swaybar stiffness table and you can see all of the relative stiffness values compared. Little changes can make a big difference. Given your relatively light springs compared to full-on coilover setups, I wouldn't consider using the larger bar.

26mm front and 24mm rear

I would go with the 24mm rear, especially if you do get the front bar.

Thanks a lot for the help guys, will go with the 26mm front and 24mm rear as suggested.

I've also been offered a Cusco Front Underbody brace. Does this item make much of a difference?

IMHO not a noticeable effect.....I would spend the money on a good drivers school instead...that WILL make a noticeable improvement

Cheers.

Which cusco brace have you been offered? The Type I or the Type II? In either case I didn't notice much difference with them at the track . Regular driving you will notice running over lane markers a bit more

I suggest regardless of which bars you buy, to install the rear first and get used to the additional rear rotation and learn and appreciate the difference. Maybe even skip the front swaybar. It is only a good deal if you wanted it before you saw/found the "deal."
