okay here's the situation....

i went and bought a set of h&r springs for my 99 accord 4 cyl. sedan...

i was told by the store owner that these were the correct springs for my car...

when i got home i went and checked the h&r website and found out that the springs that i had picked up were for an accord v6...

what i was supposed to get: part # 51853-88
and what i got: part # 51858-88

and on the reciept: all sales final... no exchange or refunds

so since i can't give them back.... i'm gonna try to put them in...

first question: will they fit? is there a major difference in the suspension design?

second question: will my performance suffer seeing as how the springs are made for a slightly heavier car?
