I just wanted to get everyones opinion on if the difference in price is really worth it. Its going to be in a Turbo GSL-SE with GC Coilovers(275lbs) and most likely Eibach(150lbs) rear springs...On my brothers Blue rx7, it has the HP's but im not sure if i should follow the same route. Im planning to occasionally take it to the track(1-2 times a year) but it will be a daily driver. Is it really worth spending double to get the adjustabilty? How much difference do the settings really make?

Thanks for any help.

 

I heard the HP's are like setting #3 on the Illumina's. Other than that I can't really help you.

You can also get like HP's for the rear and Illumina's for the front wich is harder.

 

I had a set of HP's on 350 front and 200 rear, they were struggling to get the job done, If you are going for those spring rates, I would definately recommend the Illuminas, and if you are on a budjet, at leat get them for in front, and the HP's in the back.

 

Why don't you get the illuminas and the GC 300 front and 175 rear. You're only gonna do this once. And this way you'll have the adjustabitily.

I was talking with your brother and I agree with him get fuel cell and ditch the rusty gas tank.

 

With those spring rates I think you need to go with the illuminas.
