I installed the following mod's on my Toybaru:

(1) - super-light 16" (Volks Racing TE-37, 5.2kg each) wheels and Michelin Primacy 4 205/55-16 tyres;
(2) - two-piece front brake rotors (saveing about 3kg each);
(3) -Cusco anti-roll bars (14mm and 16mm);

(1) to (3) improve ride quality significantly. If you also install GR86 stock OEM shock absorbers, ride quality will improve further.

(4) Crank pulley from Fluiddampr - this makes the engine smoother and quieter.

Then, just add sound insulation pads on doors, floor, roof and bulk-head.

The above will make the toybaru a 'touring car' without loss in performance. There are also a few other minor mods available, if you so desire:

(5) Replace the iron knuckle (or hub-carrier) with the aluminium one from GR86;
(6) Versus light-weight rear lower control arm; and
(7) SPL light-weight front lower control arm.

(5) and (7) will further reduce unsprung weight and improve handling and ride.

ACE used to make a quiet exhust system (while reducing weight and noise!), but that isn't available anymore.

I also tried taller springs from Chuhatsu, but the ride did not improve. They are only necessary if you drive on rough roads often.

Good luck.
