Day 1
Before Install... 
when to test drive at ampang lookup point/ little genting
-Road condition not all part of the road is smooth, some part of the road is patch here and there and some part of the road is deeps in maybe road patch is not very well... like this ------_________---------
-Car Condition all stock just sport rims .. 
-test run 1 stock speed up about 70kmh~90kmh, during corner the car very unstable speed was drop to 60kmh when coming downhill, during cornering the car feel like in a boat ride when wave is strong... so i backoff try not to risk 

then when to install Titan suspension

After install Titan suspension, they check the setting and have some driving around the office ...

After all the done, Titan son and me when for test drive we use some short cut road to Ampang lookup point ...
i start with slow drive to feel how it respond on slow speed at 60kmh... good ride feel like using sport spring not too stiff ...cornering is stable ...
Then i increase the speed to 100kmh ~ 120kmh in strait road and corner the feel is much more better very control suspension damping & rebound is very well set.... then we reach a part of corner with patch road with deeps in ------_______-------- is during cornering speed at that time was 110kmh... i was scare the tail of the car will let go (oversteer) cause happen to me before ... sad experince that time ... so i dint think much continue to speed dont care much ...surprise dint Oversteer at all so i continue few more corner .... hehe    really happy then on the way back to Titan office i take a 90 degree turn and jam brake during turning ... surprise the rear part of the car dint power slide off ..... even Titan son also surprise  

Day 2 testing is on hill road with high speed corner and medium speed corner road was very smooth...

Day 2 Medium speed & High speed corner ( #Dont Try this At home# )

-ride from Shah alam to Gombak toll was fine, even my co-driver dint notice i have install Titan suspension at the early stage... dint tell him about the installation ..hehe when reach road that have yellow line to slow your car speed ... it feel stiff if the yellow line is thicker at some road ... i had that ride feel even in stock suspension...

-Going up hill was fine then i told my co-driver i have install titan he was shock, he say the car dint bounce much on the slow speed and ride is confort car speed follow speed limit hehe then after the Genting tunnel i increase speed abit on the long strait downhill, after that long strait got few medium speed corner (last time on my old car max ever go is 100/kmh) then i try to push with Titan at that time was doing 130kmh ~ 140kmh got some G force feel hehe... surprice the Federal 595EVO tire dint not loss traction dint feel understeer during turning and even increase speed in the corner

-When arrive at Berjaya hill resort at the early guard house before arrive the hill up there the road surface is smooth but the tar is not so nice tire killer road ...hehe during that time my tire have reach optium temperature small stone stick on the tire when drive slow slow 20/kmh... continue to drive the road designer was very good for berjaya hill resort if drive FR can play drifting haha... continue to attack corner after corner... push and push want to feel when is the tire oversteer and understeer but it just continue give more traction really good tire
