a few questions
 

I put this in the general forum because all my questions are different topics.By the way all questions are for my 93 coupe.

1.I was wondering if anyone has just aftermarket side skirts on and if there are any that look good alone. I don't want to spend the cash for a whole kit, I don't want to change the look completely and I don't want the added weight. Pics would be great.

2. Hyjinx said an offset of 40 would look sunken in on my s13. I was wondering if anyone has used eibach wheel spacers? I was thinking that might look good and give better handling.

3.What is the fattest tire I can put on the rear with a 18X7.5 rim.

4. What is the stock exhaust piping size?

5. I'm always looking to save money so I was gonna buy the cai from ebay and use a k&n filter. Has anyone dynoed one of these. I don't see how much of a diff there can be, it's just piping.
And has anyone used the front or rear ebay strut bars? I see one sold by s-tune, front and rear for $25 plus $30 shipping. should I buy this?

1. IMO, just side skirts wouldn't look right at all. How bought a nice front lip?
2. Havent personally run any wheel spacers, but from people I know that have run them they have been happy. Also check out H&R spacers...have heard nothing but good things. There shouldnt be any plus for handling though from the spacers
3. 235, maybe a really stretched 245?
4. 2"
5. Difference is very small, but if your anal about this type of stuff go brand name.
Check for megan racing strut bars, I know a few people that have run them and they are good enough!

Does anyone have any pics of having just a front lip?

The spacers give u a wider stance therefore better handling. So they say.

i bought a front strut bar from S-tune, its pretty good quality, and you notice a slight difference in handling, i stress slightly, so go with S tune, or you could be anal and go name brand, cant go wrong with name brand...well most of the time

5) I got a 3pc set of Mookeeh strut bars off EBay. Front upper, rear upper and rear lower. The rear lower barely did anything, the front and especially the rear made a difference though.
2) If you plan to enter events make sure the spacers leave enough lug nut threads to pass inspections. You may have to get longer wheel bolts from Nissan.
