Another Coil-Over/Spring Question

Alright heres the scenario. I have a 94 Integra, it is sittin on 17's and i have Ground Control coilovers (i think, has no writing on the coils, and i bought from a nearby store. They look JUST like GC tho...) When i am driving and i hit little bumps on the road my car sounds like it is bottoming out almost, its a real loud "bam" noise. and it makes it sounds cheap. So because of this i bought some Koni Yellows, which arent on yet. But heres the thing, i went to my mechanic today to have hiom put on the Koni's, and he said that they will not help with that noise. he said that it was because i bought cheap coilovers and they werent rated to the integra (the coils fit civics, del sols, integs etc.) and he suggested that i buy springs before putting on the shocks to save some labor fees.

Now can some of you more experienced enthusiasts help me out here? should i throw the shocks on with my coils, or should i just buy the springs? (btw i am not good with putting stuff on myself so i have to pay, and its like anywhere from 75-250 to have it/them done)

BTW if Springs should i go Neuspeed Race or Sport? i mean will Race be tuckin tire? I want to be right at tire if possible.
Thanks

i was in the same position as yoou. i bought some gc look-a-like coilovers from a local shop and when i put them on everytime i hit a bump it hit hard as hell like it was bottoming out. then i decided to buy some tokiko shocks and see if that fixed it. i went for a drive and 5 mins later i realized that new shock didn't fix the problem. then after a couple of months i bought some real gc coilovers and now the ride is pretty close to stock.

thx man, ill just buy new springs. SO now....what type the Neuspeed sport or race springs? (1.7 drop or 2.25) will the race fit with my 17's?

I would say sport...I would get koni shocks though

I'm thinking Sport, IMO Race might be a tad to low.

If you want coilovers spend the $$$$$ & get the real thing. Those so called coilover sleeves are complete JUNK! I say go with the 1.7" drop & some good shocks. With the race springs you will need a camber kit & ride quality will suffer more due to the increased spring rate.
