Recently, I have driven a few different rides. 1st was an Odyssey with Bilstein. Not sure of the model. I find it comfortable and cornering not that bad. Still I have to take into consideration that Odyssey is a higher vehicle plus it's not really intended for hard cornering.
2nd was an Iswara aeroback with GAB springs only. Not adjustable coilovers but with hard bushes. To my surprise, cornering was really good and comfort wise I would say 7/10. I think I can bear with that. On the highway, on bumpy sections, I could feel the bump but it was not as bad as my friends Kancil with some lowered sports spring.
Lastly, it was a Perdana with Tein HA. This was my favourite among the three. My friend set the adjustables at the hardest setting and yet to me it was comfortable. Cornering was good. I liked it, I didn't feel scared the car would turtle. And I also like that when I change the steering direction quickly, it was like... how to put in words??? Easy I think is the word.
However, these are all from other types of cars. Not DB8. I don't know if those setting would suit my car. And consideering the Iswara's GAB springs and the price he paid for it, it's really worth it. I think I can say that the difference between Tein HA and the GAB springs were quite unnoticeable. This is just my 2 opinion.
Thanks for the tips Izso. As for now, I need to learn more about spring rates. I think I know what is that but how to choose the right one, I am still quite unclear.
