sports bow bounce problem

Hello Friends, I wore an eibach sports spring to my 1,4 207 vehicle 3,5 cm but the vehicle bounces incredibly in the pits I was officially jumping in the afternoon, I accelerated in the afternoon when I came to 140 to test it. am i Is there a mistake somewhere?

firstly welcome. What are the tire sizes?

Thank you, thanks. My 15 brothers

more precisely 185 65 R15 88 T

it shouldn't bounce that much, if it is 40 45 cheeks with the tires whatever I can say, how many springs were attached 3,5 or 5 mi

3,5 eirbach spring was installed, there was a pressed original spring, I dismantled them, I mounted them, it never bounced.

I think there may be a problem in its assembly. As I said, I should not bounce it with 3.5 cm of tires. Many of our friends used 3,5 cm in the forum. he shouldn't bounce with those tires.

if not, I'll take it again, let me see it, thanks
